The functionality is also somewhat limited on mobile. Please, be patient and check it out on desktop for the full experience.** This notebook displays play sequences (drives or possessions) for all 2009-2019 regular season [NFL](https://en.wikipedia.org/wiki/National_Football_League) drives as an interactive [Sunburst chart](https://datavizcatalogue.com/methods/sunburst_diagram.html). Each play is represented by an arc with colors corresponding to different play types. Sequences are put together by traversing concentric circles from the center outward. The angle span of each arc represents the count of plays with the corresponding sequence of previous plays. Learn more about the NFL dataset below the graph. Explore the graph by: * **hovering over arcs** to display sequence paths * **clicking on arcs** to select paths * **double-clicking on arcs** to zoom in on them and see following plays * **double-clicking on the center circle** to zoom out one step at a time or **on path arrows** on the right to zoom out to the corresponding plays * **right-clicking or long-clicking on arcs** to see distributions of sequence and event property values under the chart * **selecting properties in the "color arcs by" dropdown** to see median values for numeric properties and frequencies of most common values for categorical ones * **dragging arcs to the "target sequences" box on the left** to mark corresponding sequences as "happy"/"sad" and be able to color arcs by the probability of being on "happy"/"sad" paths * **dragging arcs to the "start" box of the path view on the right** to set the denominator of the % numbers to the count of that arc * **using the "Rules to filter & modify sequences" widget** to filter, extract sub-sequences, replace, combine and split sequences (see explanation how to use it below the graph). `34:T549,viewof arcColors = { // set up html const html = d3.create("html");

It is probably not as powerful as the languages above but that was not a goal of this exercise. The focus here is on usability rather than formal logic or performance. Note: all SPACES in query strings are ignored, so you can add them as you please for better readability. ### 1. Matching events **"()"** - matches any one event (play) **"(:pass)"** - matches one event called "pass" ("_eventName" event property) **"(:pass|:run)"** - matches one event called "pass" OR "run" **"(!:pass)"** - matches one event NOT called "pass" **"({pass_location=left, yards_gained>=3, play_result!=first_down|second_down})"** - matches one event with properties: "pass_location" equal to "left", "yards_gained" greater or equal 3 and "play_result" not equal "first_down" or "second_down". Supported operators include: "==", "=" and ":" (all represent "equal"), "!=", ">", "<", ">=" and "<=". **"[3]\\(:pass)"** - matches 3 events called "pass" in a row **"[0..3]\\(:pass)"** - matches 0 to 3 events called "pass" in a row **"[2..]\\(:pass)"** - matches 2 to more events called "pass" in a row **"[..4]\\(:pass)"** - matches 0 to 4 events called "pass" in a row **"[..]\\(:pass)"** - matches any number of events called "pass" in a row Basically, an event match pattern consists of "[...]" part encoding the possbile count of events followed by "(...)" part encoding the constraints of each event. If "[...]" part is missing, it defaults to one event ("[1]"). If "(...)" part is missing, it defaults to any event ("()"). All the above rules can be combined IN THE ORDER INTRODUCED ABOVE, for example: **"[1..2]\\(!:touchdown|:turnover|:punt {yards_gained<5, play_result!=first_down|second_down})"**. ### 2. Matching sequences of events **"[2..3]"** - matches any event subsequences of length 2 to 3 events To match a sequence of different events, separate them with one or more "-" symbols: **"(:pass)-(:run)"** - matches one event called "pass" immediately followed by one event called "run" **"[2]\\(:pass)-[..3]-(:touchdown)"** - matches two events called "pass" later followed by one event called "touchdown" with any events in between but no more than 3 of them To match the start or end of a sequence, use "|" symbol: **"|-(:pass)"** - matches one event called "pass" at the start of a sequence **"(:touchdown)-|"** - matches one event called "touchdown" at the end of a sequence There are a few rules for specifying whether a match should represent a whole sequence or only some part of it: **"-(:pass)"** - matches any sequences, which have one event called "pass" ANYWHERE inside, but ends the match at that event (equivalent to "|-[..]-(:pass)") **"(:pass)-"** - starts a match from event called "pass" but a sequence can have other events before it **"-(:pass)-(^:run)-$"** - starts a match from event called "run" but a sequence has to have an event called "pass" immediately before it **"^-($:pass)-(:run)-"** - ends a match at event called "pass" but a sequence has to have an event called "run" immediately after it **"(:pass)-[1..3]\\(^$:run)-(:touchdown)"** - matches only a 1-3 event sub-sequence of events called "run" but the sequence has to have the corresponding events before and after Similar to event properties, it is possible to specify sequence properties: **"-()- {{pos_team!=NE|SF, home_score>=10}}"** - matches all sequences (drives), where team possessing the ball was not "NE" or "SF" and the score of the home team was 10 or more. Sequence properties need to be placed at the end of a match pattern and be encompassed by double curly brackets These double curly brackets is also the place to change matching parameters: **"(:pass) {{_whereToMatch=_FIRST}}"** - extracts only the FIRST matched "pass" event for each sequence. Default value is "_ALL", which extracts ALL matches in a sequence, so it can split a sequence into several sub-sequences **"(!:pass)-(!:pass) {{_allowOverlaps=true}}"** - extracts all pairs of 2 non-pass plays in a row including overlapping ones (if "_whereToMatch" equals "_ALL"). Default value is "false", which starts the next match within a sequence after the end of a previous match Sequences match pattern syntax is easy to master, apply and read; nevertheless, it provides a powerful interface to express a wide range of sequence questions. Here are a few examples for the NFL play data: * 4th quarter drives where New England quarterback was sacked: **"-({quarter=4, play_result=sack})- {{pos_team=NE}}"** * three-and-out drives: **"|-[3]-(:punt)-|"** * touchdown drives without a single run: **"|-[..]\\(!:run)-(:touchdown)-|"** * splitting drives into first-down sub-sequences: **"({down=1})-[..]\\({down!=1})"** ### 3. Cross-referencing between events The query language supports referencing earlier events in a match pattern to compare different events between each other. For this, first you need to tag some matched event with a "custom name", which has to start with "@": **"(@ev :pass)"** - assigns "@ev" custom name to the matched event (its regular name is "pass") Later in the match pattern you can reference tagged event to compare event names and event property values: **"(@ev)-(:@ev)"** - the first and the second matched events have to have the same names **"(@ev)-({yards_gained=@ev|3})"** - the "yards_gained" property value of the second matched event has to equal to the "yards_gained" name of the first matched event or equal to 3 The full power of tagging and referencing events is explained in "Modifying sequences" and "Adding arbitrary code" sections below. ### 4. Combining match patterns into rules To further increase the number of addressable sequence questions, match patterns can be combined via logical AND, NOT and OR rules. This can be intuitively done in the rules widget (rulesWidget() function) and works as follows: **matchPattern1 AND matchPattern2**: in order, matches "matchPattern1", extracts the matches into a new set of sequences, matches it to "matchPattern2" and extracts the matches into the final set of sequences. In the rules widget AND operator is applied by adding new rules. **NOT matchPattern**: matches "matchPattern" and then filters original sequences to those, which did NOT match. In the rules widget NOT operator is applied by clicking "not" button below a match pattern. Here is an example of a match pattern for sequences, which don't contain two run plays in a row: **NOT** **"[2]\\(:run)"**. **matchPattern1 OR matchPattern2**: in order, matches original sequences to "matchPattern1", extracts the matches into a new set of sequences, matches original sequences to "matchPattern2", extracts the matches into another set of sequences and then assembles a union of the 2 extracted sets of sequences. Duplicates are removed. If _allowOverlaps=false in both match patterns, overlapping results between the 2 extracted sets of sequences are removed as well. In the rules widget OR operator is applied by clicking "or" button below a match pattern. Here is an example of a match pattern for sequences, which contain 3 runs or 3 passes in a row: **"-[3]\\(:run)-"** **OR** **"-[3]\\(:pass)-"**. ### 5. Modifying sequences Great power in exploring sequences and discovering insights can come from being able to modify sequences on the fly by replacing, combining, splitting or removing certain sub-sequences according to specified rules and then querying the new set. This can be done in the rules widget by clicking "replace" button below a match pattern and constructing a "replace pattern", which ties to the match pattern. The rule will replace all sub-sequences matched in the match pattern with the new sub-sequences constructed from the replace pattern. The match pattern should not allow matches to overlap (_allowOverlaps=false). Replace pattern overall follows the same syntax as the match patterns but cannot have any ambiguity: event counts, event names, event property values and sequence property values all need to be explicitly set to concrete or referenced values. Here is an example of collapsing first down sequences into a single event and copying over "play_attempt" property value from the first event: Match pattern: **"(@ev {down=1})-[..]\\({down!=1})"** Replace pattern: **"(:first_down_seq {play_attempt=@ev})"** There are also the following replace pattern shorthands: **"(ALL@ev)"** - copy over all events with custom name "@ev" matched to the match pattern **"(REVERSE@ev)"** - copy over all events with custom name "@ev" matched to the match pattern in the REVERSE order **"({@ev})"** - copy over all event properties from an event with custom name "@ev" matched to the match pattern **"-"** - replace with nothing, effectively removing matched sub-sequences. ### 6. Adding arbitrary javascript code Occasionally, using sequence query rules might be not sufficient to filter to desired sequences to answer a data exploration question. This can happen when we need complex event- or sequence-level property matching or modifications, for example, computing timestamp difference between events. In such cases, there is a possibility to add javascript code into match or replace patterns, which can reference custom names of the matched events and perform arbitrary computations. Javascript code can be injected in the same pattern slots as event- and sequence-level properties and needs to be encompassed by the "#" symbol. Here is a list of variables addressable in the javascript code: * **seq** - object containing all sequence-level properties * **@...** - list of events (objects) matched to the match pattern, referenced by their custom names. For example, for a set of 3 consecutive matched events with the custom name "@ev", javascript code can access the "play_result" property value of the first matched event as "@ev[0].play_result" * **nSeq** - object referencing a newly created sub-sequence by a replace pattern. Only accessible in the sequence-level properties section of replace patterns * **nEv** - object referencing a newly created event by a replace pattern. Only accessible in the event-level properties section of replace patterns. Javascript code in match and replace patterns has notable differences: * in match patterns, javascript code can only be added to the sequence-level properties section of a pattern and evaluate to a boolean condition (return true or false) * in replace patterns, javascript code can go into the event- or sequence-level properties sections and should assign values to nSeq and nEv properties. Here is an example of a match pattern with javascript code to filter NFL drives to the ones lasting 10 minutes or longer and consisting of 20 or more plays: **"|-(@a)-[..]-(@b)-| {{#(@b[0].timestamp - @a[0].timestamp >= 600) && (seq.events.length >= 20)#}}"**. Here is an example of a match+replace patterns to split "pass" plays into "pass_left", "pass_right", "pass_middle" and "pass" (when pass was attempted but direction was not known): Match pattern: **"(@ev:pass)"** Replace pattern: **"({@ev, #nEv._eventName = (@ev[0].pass\\_location) ? ('pass\\_'+@ev[0].pass\\_location) : 'pass'#})"**. `3a:T1eff,// re-organize data into an hierarchy to plot dataHierarchy = { // build hierarchy of nodes and assign data values const rootNode = { name: "start", node_id: 1, node_depth: 0, node_count: 0, target_count: 0, prop_values: [], prop_values_all: [], color_values_all: [], children: [] }; const propertyLevel = arcColors.startsWith('ev.') ?
