Rendering mode in JavaScript Heatmap chart control

Heat map can be displayed using Canvas or Scalable Vector Graphics (SVG) rendering logic to improve the initial load performance and scalability. Heat map can also be automatically switched between Canvas and SVG modes based on dataset size. You can enable this mode by
setting the renderingMode property as Auto.

If the Auto mode is enabled in the heat map and there are more than 10,000 data points, then the heat map will be rendered in a Canvas mode; Otherwise, the heat map will be rendered in a SVG mode.
