[FEAT] Decision path highlighting

[OlivierBinette]

Have the option to highlight the decision path on hover, as suggested by @nurskurmanbekov:

"Decision Path Highlighting: Develop a feature that highlights the decision path for a specific instance or group of instances in the decision tree. This can be done by visually tracing the path from the root to the leaf node(s) corresponding to the selected instance(s)."

I have come across a Tree Diagram, such as this one, that shows the proportions of each sub-group of a given variable. It could be a good feature to be able to select the attribute for which we want to trace the proportions in each node.
