First, put the effect map out: With a histogram of the basic elements: column, axis, scale, value and so on. It has to be said that D3.js is more troublesome than the echarts of direct use, but it is more free. Let's see how it's going to happen. Determine the size of the canvas var width = 400; var height = 400; Add an SVG canvas to the body-var svg = D3.select ("Body"). Append ("SVG"). attr ("wi
