Is JavaScript & SVG a valid approach for building a simple BPM Tool?

I am looking to create a simple visual workflow UI that allows you to place rectangles, include some text some text and make connections from one rectangle to another. Kind of like a flow diagram, but the thinking would be more of a business process model. https://mobdro.bio/

I have been looking at using SVG, and building a javascript application to power it, but I thought I'd bounce this idea of this group to see if it is a viable path to follow?
