d3 bootcamp

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

D3 provides 4 ways to make a transition to a graph:-Transition ()Starts the transition effect, before and after the shape changes before and after the state (shapes, positions, colors, and so on), such as:. attr ("Fill", "red") // initial color is red . Transition () // start transition . attr ("Fill", " Blue ") // End ColorD3 automatically interpolates the color values (RGB values) between the two colors (red and blue) to
