### Version 5.1.1 ### Reproduction link https://echarts.apache.org/examples/zh/editor.html?c=geo-svg-scatter-simple ### Steps to reproduce - Open the reproduction link - Watch the CPU overload in default `canvas` renderer - Switch to `svg` renderer - Watch the CPU overload and effectScatter rendering - The effectScatter's animation becomes not smooth any more ### What is expected? Lower CPU overload and effectScatter has a smooth animation ### What is actually happening? High CPU overload and the animation of effectScatter is not smooth.    ### Others **I noticed that a strange zrender level named `zr_100000` was added to the DOM.** <!-- This issue is generated by echarts-issue-helper.
