A field guide to the /lens-chart skill

AI BI Chart Type Selection

Picking the wrong chart hides the answer. /lens-chart selects type by data density, drill-down, real-time, and accessibility, anchored to a decision.

Analytics charts answer different questions than product UI charts. The dashboard chart needs density (more data points per pixel), drill-down (click to dig deeper), real-time refresh in some cases, and accessibility for the audience that includes screen readers. Picking the wrong chart hides the answer the audience needs.

The /lens-chart skill selects chart type for analytics dashboards specifically. Each chart anchors to a decision. The output covers data density threshold, drill-down support, real-time fit, and accessibility grade per chart type.

Tonone's /lens-chart skill selects chart types for analytics dashboards calibrated to density, drill-down, real-time, and accessibility.
