Add contour map functionality

Dear all

I would like to make a map of weather-like data as temperature or pressure on a folium map similar to the plot below (from https://cdoovision.com/us-temperature-contour-map/):

As it can be seen it is not a choropleth map as the contours go through the states and it is not a heatmap as I do not care how many measurements underlies this. The data I have is not gridded, but I have many individual measurements semi-randomly scattered over a large area.

Is this possible in folium currently in any way?

该 issue 未指定任何实现文件、测试或入口点。首先审查 Folium 现有的图层和数据可视化 API，以确定分散的测量值是否能够支持等值线地图；完成该工作需要定义 API，并为此类地图提供文档化支持。
