The example in this article describes how jQuery implements a multi-level relationship diagram of characters with a gradual display effect. Share it with everyone for your reference. The details are as follows:
Here is a demonstration of how jQuery implements a multi-level relationship diagram of a character with a fade-out effect. n in setQuestPose:function represents the total number of objects, r represents the perimeter, i represents the number of objects, w represents the broadband of the outer object, and h represents the outer object. The height d represents the actual angle. Please pay attention when testing. If there is an error in the lower right corner, please refresh the page.
The screenshot of the running effect is as follows:
