Chart Builder

Overview

This skill provides a systematic approach to data visualization—from choosing the right chart type for your data and message, to implementing it in Python (matplotlib/seaborn) or JavaScript (Chart.js). It covers chart anatomy, color principles, accessibility requirements, and common pitfalls, so every chart communicates its insight clearly and honestly.

When to Use

• You need to communicate a data insight visually
• You're unsure which chart type fits your data shape and message
• You need reproducible chart code in Python or JavaScript
• You want to improve a chart that isn't communicating clearly
• You're building a report, slide deck, or embedded visualization

When NOT to Use

• Building a full interactive BI dashboard (use dashboard-designer skill)
• Designing data art or infographics for marketing
• Creating maps or geospatial visualizations (use a GIS tool)
• Animating data for video production
