Tooltip can be displayed on both SVG and Canvas elements. You can directly attach the <svg> or <canvas> elements to show tooltips on data visualization elements.
Create the SVG square element and refer to the following code snippet to render the tooltip on SVG square.
<TooltipComponent content='SVG Square' cssClass='e-tooltip-css' target= '#square'>
</TooltipComponent>Create the canvas circle element and refer to the following code snippet to render the tooltip on Canvas circle.
<TooltipComponent content='Canvas Circle' cssClass='e-tooltip-css' target= '#circle'>
</TooltipComponent>import * as React from 'react';
