21:null 22:["$","title",null,{"children":"First Observable Notebook 2023: Hello \"show me another\" | Notebooks for data reporting | Observable"}] 27:T41c,Wow. Really neat, and yet so unsatisfying! But that's part of the fun of this technique. We're already honing our intuitions. What jumps out? * Lots of stops seem to take 30 min or more. Maybe. Worth looking at the distribution there. * Number of years of experience for officers is interesting, could be analyzed. * Since street is it's own variable, we could see the most active streets just by grouping on the name. * What are the possible list of agencies and how active are they? * We should definitely ask ourselves if the LGBT and perceived limited English columns actually mean much. There may be other columns like this. In a real world scenario, we might take more effort to show more columns, as well, or display this more legibly. Again, the sky is the limit here with what you show. It's such a light and simple pattern, and easy way to build up insight and find actionable paths of analysis, that you can really adapt it to all kinds of circumstances without having to do anything advanced in terms of processing or analyzing the data.28:[] 25:{"id":"7b498de1b8975077","slug":"first-observable-notebook-show-me-another","title":"First Observable Notebook 2023: Hello \"show me another\"","thumbnail":"cbfe0eb2e01737add28865391a8faa4f7ecb14a0edcb12953608dd020abb7303","access_level":"public","create_time":"$D2023-01-22T17:41:04.962Z","update_time":"$D2023-03-04T13:56:45.451Z","view_time":null,"first_public_time":"$D2023-01-22T17:41:04.962Z","has_unpublished_edits":null,"fork":false,"stars":0,"starred":false,"owner":{"type":"team","id":"25f41a0c6eb997df","login":"data-reporting-notebooks","name":"Notebooks for data reporting","avatar_url":"https://avatars-next.observableusercontent.com/569fa856126506abf5c0a37524073a11613416e690dcd2b255c82c10a72ef794","tier":"starter_2024","bio":""},"version":285,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"69810cd3cf4bf30c","login":"eads","name":"David Eads","avatar_url":"https://avatars-next.observableusercontent.com/ed73f86cbd46170a17e3bb2a06a1939ef04e5dc379b856148b769d7ac41ab78b","tier":null,"bio":""}],"members":[{"type":"team","id":"25f41a0c6eb997df","login":"data-reporting-notebooks","name":"Notebooks for data reporting","avatar_url":"https://avatars-next.observableusercontent.com/569fa856126506abf5c0a37524073a11613416e690dcd2b255c82c10a72ef794","tier":"starter_2024","role":"editor"},{"type":"individual","id":"69810cd3cf4bf30c","login":"eads","name":"David Eads","avatar_url":"https://avatars-next.observableusercontent.com/ed73f86cbd46170a17e3bb2a06a1939ef04e5dc379b856148b769d7ac41ab78b","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":2,"collection":{"id":"7602ba5bb55fd749","slug":"first-observable-notebook-2023","title":"First Observable Notebook 2023","owner":{"id":"25f41a0c6eb997df","login":"data-reporting-notebooks","name":"Notebooks for data reporting"}},"type":"notebook","body":{"titling":"auto","title":"First Observable Notebook 2023: Hello \"show me another\"","cells":[{"id":0,"value":"# First Observable Notebook 2023: Hello \"show me another\"","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"","database":"$undefined"},{"id":134,"value":"For open-ended data investigation, reviewing individual records can be a wonderful starting point for analysis and developing systemic insights and data intuitions.\n\nWe immediately start to ask questions.
