### Bug description When using the Sunburst Chart in Superset 6 with Dark Mode enabled, the “Show Total” text in the center is rendered in black, making it invisible against the dark background. Steps to reproduce: 1. Open a dashboard with a Sunburst Chart. 2. Enable Show Total in the chart settings. 3. Switch to Dark Mode. 4. Observe that the total value text is black and unreadable. Expected behavior: The Show Total text color should automatically adapt to the current theme: - White (#FFFFFF) in Dark Mode - Black (#0E1020) in Light Mode ### Screenshots/recordings Light mode: <img width="800" height="648" alt="Image" src="https://github.com/user-attachments/assets/2e7b6714-805f-45c5-b4a2-ea42aa0717e7"; /> Dark mode: <img width="800" height="607" alt="Image" src="https://github.com/user-attachments/assets/8b845d1f-4db4-417e-bd8a-0ead161241d2"; /> ### Superset version 6.0.0 ### Python version 3.11 ### Node version Not applicable ### Browser Chrome ### Additional context - The issue only affects the Sunburst Chart; other charts (Sankey, Heatmap, Bar, Line) adapt correctly to dark mode. - This is caused by the “Show Total” text being rendered inside the ECharts canvas with a hardcoded black color, which does not respect the Superset theme tokens. - Currently, there is no way to change this color via JSON metadata, theme overrides, or CSS. Suggested fix: - Make the text color of “Show Total” dynamic based on the theme. - Ideally, it should read the current theme (light/dark) and use the appropriate contrasting color. ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [x] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
