Tasks are broken down into Actions and Targets Abstracting tasks at overall visualization **Analyze** This visualization serves the purpose of (_Discovering_) information. **Search** In terms of searching it has the elements of
1. **` Browse:`** When users want to know the team with the highest revenue, value or team with the most league titles(Location known, target unknown)
2. **`Locate:`** When users want to know the ranking of any team(Target known, location unknown) **Query** On the query level, it can be used to Identify and Compare 1. **` Identify:`** When users want to know which is the team with the most or least revenue
2. **` Compare:`** When users want to compare two teams based on the available attributes Abstracting at the Task level 1. **T1:**
(_Insight_): Manchester United is the most valued team but does not generate the highest revenue. It is ranked third after Manchester City and Liverpool Football Club
Identify the team that is valued the most and the team with the most revenue
Sub-task 1: (_Identify_) the team that is valued the most(_Extremes_)
Sub-task 2: (_Identify_) the team this has the highest revenue(_Extremes_)
Sub-task 3: (_Compare_) the teams in the first position after sorting 3. **T2:**
(_Insight_): Everton has won 9 League titles but is ranked at 8th and 10th position in Value and Revenue which is way below compared to Manchester City which has won only 8 League titles Locate the position of Everton and the neighboring team, sorting by league title
Sub-task 1: (_Distribute_) the teams based on the number of league titles held
Sub-task 2: (_Locate_) Everton and (_Browse_) for the team that is ranked below Everton
Sub-task 3: (_Compare_) Everton and the team below it in terms of revenue and valuation 4. **T3:**
(_Insight_): The difference in valuation of the most and least valued teams is massive. Manchester United is valued 97.6% more than Bournemouth Compare the valuation of most teams
Sub-task 1: (_Browse_) for the teams with the highest valuation
Sub-task 2: (_Browse_) for the teams with the lowest valuation
Sub-task 3: (_Compare_) the difference(_Extremes_) in the valuation and derive the difference percentage32:T52d,## Critique The visualization is good on its own and conveys the point and comparisons between teams clearly. I think it is brilliant to show all three pieces of information on the same chart and the Convenience of sorting as the options are present in the middle of the chart. The visualization totally justifies the data to be represented. Improvement: The visualization on its own has many to be components. I would break down the revenue into a different frames. Since three changes are happening at the same time, the users might find it difficult to notice the changes that occurred upon sorting or selection.
The ordinate of the chart could have been made to change based on the sort by value. For example, the values remain static for value and when I sort by revenue, the ordinate values are still in terms of billions and changed to match the revenue scale. This might confuse the users if they don't know where to look for revenue. **Feedback by tasks:**
1. T1: This visualization very clearly lets the user know the teams with the highest value and highest revenue 2. T2: This visualization lets users rank teams by league titles and show the revenue position simultaneously which is easier for users to derive the insight 3. T3: The idiom chosen for this insight is perfect to compare the extremes 33:[{"id":"e51b32f4937ed23075ea95c9081e0b1751cefde28ff35f45f3ad6f5a87c9a9bd3e711ad385d0b6532eec83ac8801d577efae3738bab088379087b67b5ac1e4f3","href":"https://static.observableusercontent.com/files/e51b32f4937ed23075ea95c9081e0b1751cefde28ff35f45f3ad6f5a87c9a9bd3e711ad385d0b6532eec83ac8801d577efae3738bab088379087b67b5ac1e4f3","name":"Viz.png","type":"image/png","lastModified":1675812966178.585,"size":630497},{"id":"b02f01b59ad9d91946732e32d3cababb33014ae2e1905a78dc5b394f2dcd06294edb71e1217764102de564581bc7b6e9b47447ec1fc4836acdd19a8b68af4869","href":"https://static.observableusercontent.com/files/b02f01b59ad9d91946732e32d3cababb33014ae2e1905a78dc5b394f2dcd06294edb71e1217764102de564581bc7b6e9b47447ec1fc4836acdd19a8b68af4869","name":"Insight2.png","type":"image/png","lastModified":1675904702507.945,"size":599680}] 2f:{"id":"4e4f772b5b23a7d1","slug":null,"title":"Manchester United is the most valued team but does not generate the highest revenue","thumbnail":"ebdc81bd77fb094786010c65975f884c42c991d37359d5b800377d9fc7ad437b","access_level":"public","create_time":"$D2023-02-07T21:53:17.654Z","update_time":"$D2023-02-22T17:39:40.024Z","view_time":null,"first_public_time":"$D2023-02-07T21:53:17.654Z","has_unpublished_edits":null,"fork":false,"stars":0,"starred":false,"owner":{"type":"team","id":"e76678b312b62ab3","login":"akhila","name":"Akhila Sulgante","avatar_url":"https://avatars-next.observableusercontent.com/2e264e285632a44937edf6eb6b531fffbd152d07233e70f4c70c2cd9a5cd9e09","tier":"starter_2024"},"version":133,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"667daa7e86be0e8e","login":"akhila","name":"Akhila Sulgante","avatar_url":"https://avatars-next.observableusercontent.com/2e264e285632a44937edf6eb6b531fffbd152d07233e70f4c70c2cd9a5cd9e09","tier":null}],"members":[{"type":"individual","id":"667daa7e86be0e8e","login":"akhila","name":"Akhila Sulgante","avatar_url":"https://avatars-next.observableusercontent.com/2e264e285632a44937edf6eb6b531fffbd152d07233e70f4c70c2cd9a5cd9e09","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":0,"collection":null,"type":"notebook","body":{"title":"Manchester United is the most valued team but does not generate the highest revenue","cells":[{"id":0,"value":"# Manchester United is the most valued team but does not generate the highest revenue","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined","output":"","database":"$undefined"},{"id":9,"value":"This notebook is to demonstrate an understanding of the Data Visualization Problem Abstraction using Tamara's grammar.\n\nThis Visualization is created by [Akhila Sulgante](https://akhilasulgante.github.io/portfolio) as a part of [CS 7295 class](https://johnguerra.co/classes/data_visualization_spring_2023/) at Northeastern under the guidance of [prof.
