A chart that intuitively expresses system status and Network Traffic Transmission

D3 is a chart class library based on JS and SVG, which has rich examples. I wanted to find a ready-made one to express the system status and network traffic transmission. Unfortunately, this one that is the closest to the requirement only supports the tree structure using d3.js to visualise hierarchical classification, so I made some changes myself. effect:

Features:

Supports both tree and mesh Structures

Nodes can be dragged, And the location information is retained after the data is refreshed
