Manually set the initial position #7

Open WYanChao opened 5 years ago

WYanChao commented 5 years ago

Hi, Is it possible to have an API to set the initial position of each node? I understand that this d3-voronoi-treemap is based your previous d3-voronoi-map. The reason to add this API is that your current voronoi treemap is not suitable for dynamic hierarchical data.

My current solution is to set the .prng to a seedable PRNG for dynamic hierarchical data and generate them separately. I don't think it is an efficient way to update the voronoi treemap.

Thanks.

I rephrase your first comment in order to be sure to well understand it.

Your use case is:

  1. you have n data, each with their own v value
  2. you compute a first Voronoï treemap
  3. you update the values of your data: you still have the same n data, but now each defining v' value

==> your need is to be able to update the already computed Voronoï treemap in order to reflect the new v' values ==> you propose to introduce an initial position API, so that you can compute a second Voronoï treemap by reusing the position of the first Voronoï treemap

Am I right?

Thanks very much for your reply.

Yes, it is exactly what I want.
