Scatter of merged PRs in the selected period, plotting lines changed (log scale) against review comment count. Each dot is one PR, colored by size bucket. Click any dot to open the PR on GitHub.

Why it matters

A healthy review process scales attention with change size. This chart surfaces where that relationship breaks.

What to look for

  • Bottom-right outliers (big PR, no comments) — review blind spots worth auditing. Risky changes went in without scrutiny.
  • Top-left outliers (tiny PR, many comments) — contentious changes, unclear conventions, or new contributors who need support.
  • Clean diagonal — attention scales with size. That’s the signal you want.

How the chart is built

  • Horizontal axis: total lines added plus deleted on the PR.
  • Vertical axis: comment count on the PR (threads and discussion Sweetr attributes to that PR).
  • Color: the same size bucket you use elsewhere (Tiny through Huge), based on lines changed and your workspace thresholds.
  • To keep the chart responsive, it includes at most the 2,000 most recently merged PRs in the selected range.
