Summary

Implements heatmap-correlation for bokeh library.

Parent Issue: #53
Sub-Issue: #57
Attempt: 1/3

Implementation

  • plots/bokeh/custom/heatmap-correlation/default.py
  • Creates correlation matrix heatmap using rect glyphs
  • Diverging color scheme (RdBu reversed) centered at 0
  • Text annotations showing correlation values
  • Colorbar legend
  • Hover tooltips with detailed correlation values

Technical Notes

  • Uses rect glyphs since bokeh doesn't have native heatmap support
  • PNG export requires selenium and webdriver (fallback to HTML provided)
  • Implements all required parameters from specification
  • Proper input validation and error handling

Testing

✅ Implementation runs successfully
✅ HTML output generated and verified
✅ All visual requirements met (colors, annotations, grid)

- Add heatmap-correlation specification
- Implement correlation matrix heatmap using bokeh rect glyphs
- Support diverging color scheme centered at 0
- Add text annotations for correlation values
- Include colorbar legend

Note: PNG export requires selenium and webdriver. HTML output works without additional dependencies.
