Alexander-txj opened a new issue #13909: URL: https://github.com/apache/incubator-echarts/issues/13909
### What problem does this feature solve? Recently, I am doing industrial drawings, and I need to realize the contour map of the polar coordinate system. Finally, only d3-contour can be used. I think the application of contour map is still very extensive and can be put in echarts. ### What does the proposed API look like? You can refer to Python Matplotlib <!-- This issue is generated by echarts-issue-helper. DO NOT REMOVE --> <!-- This issue is in English.
