Velocity chart (implementation) DUPLICATE

Problem to solve

Velocity is widely used as a measure of productivity in the software development industry. In fact, GitLab itself publicly talks about the concept of velocity. It seems there is clear demand for an interface that would help users understand Velocity in GitLab.

Proposal

On the "Issues Analytics" page, add a "Velocity" chart. This chart should show the total issue weight, grouped by month, of the issues closed in the past 12 months.

Out of scope

• 2nd line for average
• Filters
• Issue list/table under the chart

Implementation

• backend #229050 (closed)
• frontend #229051

See the discovery issue for more details.
