Incredible feature! Great work! Will give the organization all kinds of insights and broader perspectives on business operations with minimal effort. Love it! 
Great suggestions in the previous comments above. 
Here are some further suggestions:
- To improve audience understanding of what is being communicated, I would prefer if (No section) would only be visible when it exists (>1). I have a project now where it’s 0 and not even visible in the list view but still presented as the first column in the chart.
- Configure sections(or section type), to include or not, like the original progress chart.
- Subtask completion chart per assignee, while in this project.
- Copy/paste charts from other projects into other communication formats like, conversation description and/or stories in tasks.
Thanks, great job @Ben_Watkins, and team!
