Allow filer/focusing on a node and its neighbours dynamically in SVG

[blipper]

SVG generated images have clickable URLs (great!). However working on large diagrams with many connections (e.g. C4 System Landscape Diagrams) it would be nice to provide clickable functionality (maybe shift-click or a right click) functionality to only hide all nodes except the clicked node display a node, its edges, and immediately connecting nodes.

@startuml
package Z {
    A->B
    A->C
}
C->D
D->A
E->F
F->B
@enduml

If I shift-clicked or whatever on A it should display the following by hiding the other nodes

It should keep the nested packages however.

This needs #925 as a prequisite.

[blipper]

Implemented in #930

Node, edges and 1 distance nodes with mouse over will be set to opacity 1.0 and the everything else will be set to lower opacity.

Hello @blipper,

Thanks a lot, very good enhancement... 👍

Is it cumulative with:

• 475

• 478

or independent ?

Regards.

Interesting. That code didn't work for me which is why I wrote this. I was using C4 UML that has a bunch of nested elements and you need the containers in other to capture the logical nesting structure I think?

Just wondering it there is any update on this. I'm also looking for this functionality for my C4 diagrams. It's unclear to me how to use the functionality added in #475 in the first place.

Hi, any plans to include this feature in public release? Now I have to deal with messy diagrams and really would like not to go the path of simplifying or dividing into multiple separate diagrams. Having one with some level of interactivity would be awesome.

I'm confused here. The pull requests #475 and #478 have been merged in public release. You should probably open a new issue if you are expecting something else and describe it precisely. Thanks!

The pull requests https://github.com/plantuml/plantuml/pull/475 and https://github.com/plantuml/plantuml/pull/478 have been merged in public release.

Just to complete. The below PR have been also merged in public release:

• 925

• 930

And some help pages must be improve... to explain how to use... _:construction: A next work (When I will have time...) :constructionworker:

Not related but avoid -> arrow and prefer --> ones.

Thanks! Looked at the code and got it working with !pragma svginteractive true.

With #1713 filtering is working (not directly in this window but if you open link to svg in a new window)

I only see that the package is not displayed in filter mode. But if this is not an issue then this issue could be closed too.
