Ability to draw a path automatically based on the given selected node info #8

Closed venki227 closed 5 years ago

venki227 commented 5 years ago

Use case: I created a scatter plot and implemented a lasso selection on it. Let's say I have a nodes with names as [1, 2, 3, .....10]. Now I am able to select the nodes 2,3,7,10 using lasso and stored this values in a array. Now I want to invert this operation, like when I give a array of nodes is it possible to draw a path around these given nodes? Please see below image

@skokenes Please let me know. Is this possible?

In this plugin, it is not possible but more generally you should be able to accomplish this in your visualization using d3 and a hull algorithm like the following lib: https://github.com/AndriiHeonia/hull
