需求

如图所示需要自定义节点的图标展示

分析

首先需要 symbol 属性添加引入
需要用到一个工具：http://tu.chacuo.net/imagetodataurl

这里是我的几个图片转出来的svg

export const lineColors = [
  '#FF5360',
  '#45CB85',
  '#EEB902',
  '#9CEC0F',
  '#FF9562',
  '#1e90ff',
  '#464DE4',
  '#FF9CDE',
  '#3591CE',
  '#9A2EF0',
  '#4DE2F8',
]
export const randomColor = (index) => {
  if(index!==undefined &&  index<=10)
    return lineColors[index]
  else {
    let r, g, b;
    let tape;
    r = Math.floor(Math.random() * 256);
    g = Math.floor(Math.random() * 256);
    b = Math.floor(Math.random() * 256);
    tape = "rgb(" + r + "," + g + "," + b +")";
    return tape; 
  }
}
export const svgPath = (index) => {
