This skill allows users to create statistical visualizations like bar, line, scatter, heatmap, area, radar charts, and word clouds by providing data in a structured JSON format compatible with Vega-Lite and Vega specifications. It guides users through syntax rules, common pitfalls, and provides a rich set of examples for diverse chart patterns and data transformations.
License
- critical:License usabilityThe license is stated as GPL-3.0 in the README.md. While this is an OSI-approved license, GPL-3.0 is a strong copyleft license that may have downstream implications for commercial use or redistribution, potentially limiting usability for some users. However, the license text itself is clear and the source code is available.
Versioning
- warning:Release ManagementThere is no version field in the manifest files (SKILL.md, package.json), no GitHub releases, and no CHANGELOG.md. The README.md does not provide specific installation instructions that would allow for version pinning, implying the use of 'main' or the latest commit.
