If you are interested in D3.js or data visualization, welcome to www.ourd3js.com for discussion. Next I will discuss how to select elements and use data.The page now contains three lines of text with the code: Hello World 1Hello World 2Hello World 3 Defines a set with three elements: var set = ["I like dog","I like cat","I like snake"]; Use these three strings to give the preceding three strings respectively.

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
