Both canvas and SVG can be used for visualization, but they differ in their strengths and weaknesses.
canvas: is a pixel-based rendering engine that uses the J**Ascript API to draw images on canvas, and its advantages include:
Canvas renders quickly and is suitable for handling a large number of images and highly dynamic images. Pixels can be manipulated directly, creating high-quality, smooth animations. Canvas can be used to implement complex games, 3D effects, and more. But it also has some drawbacks:
The canvas can only draw bitmaps, and if you need to draw vector graphics, you need to use other tools to convert them to pixel images. The canvas doesn't support event handlers and can't bind events for drawn objects. Because canvas is a pixel-based rendering, it is difficult to scale and may affect the quality of the image. svg: is a vector-based graphics format that can draw images in the browser using XML and the J**Ascript API, and its advantages include:
SVG is a vector-based graphics format where images can be infinitely upscaled without distortion. You can add an event handler to your SVG image for interactivity. Styling can be controlled via CSS, making SVG images more flexible. SVG images can be embedded directly into HTML documents without the need for additional **. But it also has some drawbacks:
SVG rendering is slower and is suitable for handling a small number of images and a small number of dynamic images. SVG images can cause performance issues when working with complex graphics. Since SVG is a vector-based graphics format, it is relatively complex and can result in large file sizes. Contrast
