d3-viz

Creating interactive data visualisations using d3.js. This skill should be used when creating custom charts, graphs, network diagrams, geographic visualisations, or any complex SVG-based data visualisation that requires fine-grained control over visual elements, transitions, or interactions. Use this for bespoke visualisations beyond standard charting libraries, whether in React, Vue, Svelte, vanilla JavaScript, or any other environment.

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable body with excellent executable examples and a clear core workflow, but it underuses its own bundle files by inlining pattern and scale material that already lives in references/, and it misstates asset filenames.

Suggestions

Move the detailed pattern catalog (bar/line/scatter/chord/heatmap/pie/force-directed) and the scales reference out of SKILL.md and point to references/d3-patterns.md and scale-reference.md instead, keeping only a concise quick-start inline.

Fix the asset filenames in the Resources section to match the actual bundle files (chart-template.jsx and interactive-template.jsx, not .js).

Tighten the Overview to remove general d3 background Claude already knows, and consolidate the 'Consider alternatives' list or remove the single-item placeholder.

Dimension	Reasoning	Score
Conciseness	The ~820-line body inlines a full pattern catalog (bar, line, scatter, chord, heatmap, pie, force-directed) and a complete scales reference that duplicate the existing references/d3-patterns.md and scale-reference.md, alongside a mildly padded Overview.	3 / 5
Actionability	Provides copy-paste-ready, complete functions (e.g. drawBarChart, drawHeatmap, drawChordDiagram) covering the common visualisation cases with executable d3 code.	5 / 5
Workflow Clarity	A numbered Core workflow (set up d3, choose integration pattern, structure code, responsive sizing) gives a clear sequence, plus a Common issues section for recovery, though explicit validation checkpoints are not called out.	4 / 5
Progressive Disclosure	References and assets are listed in a Resources section, but the pattern examples and scales reference that have dedicated bundle files are inlined in the body rather than offloaded, and the asset filenames are misstated (chart-template.js / interactive-template.js vs the actual .jsx files).	3 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that clearly defines both what the skill does and when to use it, with concrete trigger terms and a well-delineated niche. Only minor keyword-coverage gaps prevent a perfect score on trigger term quality.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions across visualisation types ('custom charts, graphs, network diagrams, geographic visualisations') with comprehensive coverage of the d3 niche.	5 / 5
Completeness	Explicitly states the 'what' ('Creating interactive data visualisations using d3.js') and the 'when' via concrete triggers ('should be used when creating...', 'Use this for bespoke visualisations beyond standard charting libraries').	5 / 5
Trigger Term Quality	Natural user terms like 'charts, graphs, network diagrams, geographic visualisations' plus framework names give good coverage, though a few synonyms/variations are absent.	4 / 5
Distinctiveness Conflict Risk	The 'bespoke visualisations beyond standard charting libraries' framing carves a clear niche distinct from generic charting skills, with minimal conflict risk.	5 / 5
