Comment:
Great work! I loved the spring-electric layout with auto-max (that's how I
imagined it all along). Everything worked as expect, so the patch is
basically ready to go. However, since we are making basically an User
Interface, I have some comments on the design decisions.
I am mostly guided by the mantra that passing UI decisions to the user is
not a solution. We should man up and fix the most useful behavior that 99%
of users will use (and maybe add the sliders hidden behind a "tweak"
button or skip them all together).
- Correct me if wrong but Live with auto-max, spring-el. and default
sliders give exactly what I expect on 99% of the graphs. I suggest we make
this default (and get rid or hide everything else).
- Similarly, I see no reason for live behavior that shoots vertices out of
screen. Link auto-max along with live. At the same time, when graph is
paused (not live) auto-max should be off.
- Numbering for vertices should be off by default (graph theorists seldom
number their vertices).
- I see only two useful vertex sizes, one for unnumbered vertices and one
for numbered. The vertex size slider can be skipped (or hidder by "tweaks"
button).
- Unnumbered vertices should be filled black.
- There should be a warning (use JS confirm) with circle layout, since it
can potentially destroy a carefully planned layout and there is no undo.
