+- [31582](https://github.com/apache/superset/pull/31582) Removed the legacy Area, Bar, Event Flow, Heatmap, Histogram, Line, Sankey, and Sankey Loop charts. They were all automatically migrated to their ECharts counterparts with the exception of the Event Flow and Sankey Loop charts which were removed as they were not actively maintained and not widely used. If you were using the Event Flow or Sankey Loop charts, you will need to find an alternative solution.
