1. Funnel Chart: Contributor Levels & Drop-offs

This funnel visualization displays contributors at different engagement levels within the project and tracks their drop-offs between stages.

Purpose

Helps identify bottlenecks in contributor progression and understand where contributors disengage.

Structure

The funnel is divided into two parallel views:

Contributors Funnel – Shows how many contributors exist at each level.
Drop-offs Funnel – Displays the number of contributors lost at each level transition.

Levels

New Contributors – First-time contributors who have just joined or made their initial interaction.
Active Contributors – Contributors actively engaging in discussions, issues, or code reviews.
Core Contributors – Key members consistently contributing and leading initiatives.

This visualization makes it easy to spot where retention can be improved.

2. Radar Chart: Contributor Activities Distribution

This radar chart visualizes the distribution of contributors across various activity dimensions.

Purpose

Provides a quick snapshot of where contributors are spending their efforts in the project.

Dimensions include (example categories)

Issue Reporting
Pr merging
Pr opening
Pr commentors

By analyzing this chart, project maintainers can understand contributor focus areas and where more engagement is needed.

…06/8Knot into contributor_engagement

…kshatb2006/8Knot into contributor_engagement" This reverts commit c2a4776, reversing changes made to 4b4f0a7.

- Updated query to use augur_data.contributor_engagement table instead of non-existent tables - Fixed schema references (tables were in public schema, not augur_data) - Improved funnel logic to show proper progression: All Contributors -> Basic Engagement -> Deep Engagement - Query now returns meaningful data instead of empty results

- Added n_repolist_uses=3 to caching_wrapper call to properly handle multiple %s placeholders - This should resolve the 'tuple index out of range' error in worker execution

each card should be its own file

Both the cards are connected, so we put this in the same file. Do you want us to create seperate file for putting gc_contributor_dropoff?

Each of the graph info descriptions should be a lot more detailed, especially with how complicated each of the graphs are. It should go into what data goes into the graph and how it is being displayed or. The lottery factor graphs would be a good example to look into or see how project velocity links to a much more thorough description of the graph. I will be able to give a better review once the query is able to populate the graphs. Please add more comments to your code as well so a reviewer can understand your preprocessing steps.
