Skill-guided chart added a debounced 250ms resize handler, viewBox-based responsive scaling, and an accessibility/colorblind-palette checklist - details a freehand D3 answer skipped; D3 basics are already solid in the baseline so the gap is real but not night-and-day.

What D3.js Visualization does

Provides D3.js workflow patterns for building interactive, responsive charts and dashboards - margin conventions, scale/axis setup, tooltips, transitions, debounced resize, and an accessibility checklist. Triggers on requests for custom D3 charts, dashboards, network graphs, or geographic/time-series visualizations; correctly defers to Chart.js/matplotlib for simple or static chart requests.
