Later I found that the file was too large for 2,364 KB, and of course this ensures that the map is accurate, but we don't usually need that exact boundary, so it's necessary to narrow it down. Fortunately, there have been predecessors to do this work, really walnuts, posterity, here to express our thanks.Conversion method:1. Op

By using d3 and js to visualize data, data can be separated from code to facilitate data modification in the future. This time, a five-dimensional Radar chart is drawn using d3.js, which compares the five attributes of multiple objects on one map. Data is written into data.csv1_data source and written into the type.csv file. Shows the effect. Source code connection: http://download.csdn.net/detail/s
