Dashboards get graded here.

DashLint is 46 rules for chart choice, layout, color, and type — written from real production dashboards, not stock templates. Point any MCP client at one URL, no signup, no API key.

Two of the 46 rules, caught in the act: pie charts over three slices should be bars (R-CHART-01), and charts need at least 12px of margin from the card edge (R-SPACE-03).
