在谷歌上搜索时，我在http://teropa.info/blog/2016/12/12/graphics-in-angular-2.html上找到了关于SVG和Canvas的使用和压缩的很好的解释

希望能有所帮助:

SVG, like HTML, uses retained rendering: When we want to draw a rectangle on the screen, we declaratively use a element in our DOM. The browser will then draw a rectangle, but it will also create an in-memory SVGRectElement object that represents the rectangle. This object is something that sticks around for us to manipulate – it is retained. We can assign different positions and sizes to it over time. We can also attach event listeners to make it interactive. Canvas uses immediate rendering: When we draw a rectangle, the browser immediately renders a rectangle on the screen, but there is never going to be any "rectangle object" that represents it. There's just a bunch of pixels in the canvas buffer. We can't move the rectangle. We can only draw another rectangle. We can't respond to clicks or other events on the rectangle. We can only respond to events on the whole canvas. So canvas is a more low-level, restrictive API than SVG. But there's a flipside to that, which is that with canvas you can do more with the same amount of resources. Because the browser does not have to create and maintain the in-memory object graph of all the things we have drawn, it needs less memory and computation resources to draw the same visual scene. If you have a very large and complex visualization to draw, Canvas may be your ticket.

For your purposes, I recommend using SVG, since you get DOM events, like mouse handling, including drag and drop, included, you don't have to implement your own redraw, and you don't have to keep track of the state of your objects. Use Canvas when you have to do bitmap image manipulation and use a regular div when you want to manipulate stuff created in HTML. As to performance, you'll find that modern browsers are now accelerating all three, but that canvas has received the most attention so far. On the other hand, how well you write your javascript is critical to getting the most performance with canvas, so I'd still recommend using SVG.

只是我对divs选项的意见。

《Famous/Infamous》和《samyazare》(可能还有其他游戏)使用绝对定位的非嵌套divs(带有非繁琐的HTML/CSS内容)，结合matrix2d/matrix3d进行定位和2D/3D转换，并在中等移动硬件上实现了稳定的60FPS，所以我不认为divs是一个缓慢的选择。

Youtube和其他地方有大量的屏幕记录，高性能的2D/3D东西运行在浏览器中，所有东西都是一个DOM元素，你可以在上面检查元素，60FPS(混合WebGL用于某些效果，但不适用于渲染的主要部分)。

为了补充这一点，我一直在做一个图表应用程序，最初是从画布开始的。该图由许多节点组成，而且它们可以变得相当大。用户可以在图中拖动元素。

我发现，在我的Mac上，对于非常大的图像，SVG更好。我有一台MacBook Pro 2013 13英寸Retina，它在下面的操作非常好。图像是6000x6000像素，有1000个对象。当用户在图中拖动对象时，canvas中的类似结构对我来说是不可能进行动画化的。

在现代显示器上，您还必须考虑不同的分辨率，在这里SVG免费为您提供了所有这些。

虽然上面的大多数答案仍然有一定的道理，但我认为它们值得更新:

Over the years the performance of SVG has improved a lot and now there is hardware-accelerated CSS transitions and animations for SVG that do not depend on JavaScript performance at all. Of course JavaScript performance has improved, too and with it the performance of Canvas, but not as much as SVG got improved. Also there is a "new kid" on the block that is available in almost all browsers today and that is WebGL. To use the same words that Simon used above: It beats both Canvas and SVG hands down. This doesn't mean it should be the go-to technology, though, since it's a beast to work with and it is only faster in very specific use-cases.

恕我直言，对于今天的大多数用例，SVG提供了最好的性能/可用性比率。可视化需要非常复杂(就元素数量而言)，同时又非常简单(每个元素)，这样Canvas和WebGL才能真正发挥作用。

在这个类似问题的答案中，我提供了更多的细节，为什么我认为这三种技术的组合有时是最好的选择。
