 Generally speaking, Canvas is suitable for cases where there is a large amount of graphical elements (usually due to a large amount of data points), like heatmap and lines or scatter plot with large data in geo or parallel coordinates. In addition, it supports some [special visual effect](${websitePath}/examples/en/editor.html?c=lines-bmap-effect) not supported by SVG. However, in some other scenarios SVG has some critical advantages: it consumes less memory than Canvas (especially in mo [...]

-In the example above, the SVG renderer provides better FPS performance in mobile devices. In some other scenarios with large amounts of data or with certain kinds of user interaction, the SVG renderer is still not as good as the Canvas renderer in performance, but two options provide the ability to optimize the performance according to the requirements of each developer.

 ## How to use specify a renderer?
 
 ECharts uses Canvas by default. If a user intends to use the SVG renderer, the module of the SVG renderer should be included in ECharts bundle.
