Polar contour plot / Contourpolar request

Hi!

Your plotting library is really awesome! Thanks for that!

I'm currently trying to make the switch from matplotlib (for Python plots) to Plotly (also Python) and I was looking for an option to display contour plots in a polar coordinate system.

I came across the following issue in plotly.py where @emmanuelle suggested to create a post here in plotly.js.

Do you guys have the intention of creating a Contourpolar type of chart? Similar to the plot show below (created in matplotlib):

I've tried the Barpolar option, but it's not sufficient for the amount of detail I would like to visualize (a 360 degree water surface elevation plot), I think the plot I would like to display greatly benefits from being a contour plot.

Thanks in advance,
Sil

该 issue 没有指出文件、测试或入口点。首先跟踪 Plotly.js 如何表示 polar 和 contour trace，然后确定 Contourpolar 图表所需的范围。完成的标准是：contour plot 可以在极坐标中显示详细数据，并且相关测试对此有覆盖。
