I want to draw a ring chart

I think https://gojs.net/latest/samples/pieCharts.html does what you want, except you need to adapt the makeGeo function so that it returns a Geometry that is what you want. The makeAnnularWedge function in https://gojs.net/latest/samples/radialPartition.html does something similar to what you want, although the geometries are centered differently.

Create the semi circle around the node with multiple fill colors, on need

[Mithun] : We want to do this while we are highlighting a node. [Mithun] : Yes, we can have multiple nodes highlighted at a time. [Mithun] : Not when node is selected, when there is some external function calling the highlight. [Mithun] : Yes. [Mithun] : Colors and number of sections will be determined by data property and yes the number of such sections could change per node.
