How to use pyecharts to draw Geographic scatter Map
Editor to share with you how to use pyecharts to draw a geographical scatter map, I hope you will gain something after reading this article, let's discuss it together!
1. Background
Make use of the Shanghai 7000+ office building project, including the project name, geographical location, daily rent, building area and the business district where the project is located, now let these projects be located on the map according to longitude and latitude, and show the rent by color, there are many things to do before operating ArcGIS software, this time, ready to try the pyecharts module, directly generate with python script.
two。 Effect picture
The effect picture is roughly as follows:
