How to edit a custom visualization?

[AriZadok]

Hi,

I don't have any coding experience, but I would like to edit one of the custom visualizations I've found (Force-Directed Graph) in order to change the functionality a bit.  Specifically, I want the nodes to be manually adjustable so that I can nail them down to a specific location, instead of their location just being dictated by the charge.

Can anyone help me figure out what I would need to learn in order to edit the code for that viz, and how to go about doing it?

Thanks very much!

You should learn TypeScript and D3.js API to modify PowerBI-visuals-ForceGraph.

Are type script and D3.js API helps modify other custom visuals aswell or just that specific visual? Thanks

Hi @ramireddy_karri - the vast majority of custom visuals are developed using TypeScript. Some are written in R but even that is built upon a TypeScript-based framework.

TypeScript is essential learning for custom visual development. d3 is a library that sits on top - a lot of visuals are developed using d3 and it does make things easier but it's not necessarily required.

Good luck!
