Display node descriptions about dark-matter-graph

Another possibility is to display description at a fixed location (say on a side column), not using tooltips.

Does the tooltip disappear when mouse hovers out? Or does it disappear when click happen at a different location?

I think it disappears when a click happens at a different location (i.e., a different node or white space around nodes). This would be similar to how the matrix boxes stay highlighted on click until a click is made on a non-colored box.

Hmm, but in that case, the user won't be able to get a highlighted view without the tooltip's interference, right?

Current case:

• mouseover: paths are highlighted, tooltip appears
• click: nothing happen visually, but the paths are remembered
• mouseout: paths remain highlighted, tooltip disappears
• click somewhere else: paths dim.

Tooltip on click case:

• mouseover: paths are highlighted
• click: tooltip appears
• mouseout: nothing happen visually (paths remain highlighted; and tooltip remains visible)
• click somewhere else: paths dim, tooltip disappears

I feel the current case is more nature?

I didn't even realize that you could click to keep paths highlighted. Now that I know about it, I find it confusing that I can have multiple paths highlighted at once (the previous one that I clicked on, and the current one that I'm mousing over).

I like the fixed location idea (i.e. the sidebar suggested in the original comment). I think this could also allow us to display much more information that would be possible with a tooltip.
