Call for action for Roassal

Dear community,

As you may have seen, Roassal has entered a stabilization phase. The book AgileVisualization.com will soon be released. After its release, Roassal will go over a new development phase. In order to prepare it, I am asking this question:

What are the 3 aspects you would like to see improved in Roassal?

You can answer publicly or by sending private messages.

Kind regards,
Alexandre

Re: Call for action for Roassal

Hi Alexandre,

In a wonderful world, I would like:
- a real graph layout (like in graphviz) that can take into account around hundred nodes and several hundred of edges and place the nodes in order to see something. Currently, I have to use the circle layout and it looks strange.
- the possibility to place hangout of the edges on nodes (as box) more flexible. Indeed, I am reverse engineering a database containing around 80 tables and lot of foreign keys and the result is not readable since the edge are orthogonal starting from the top or the bottom of the box corresponding to the column name. I would like a real entity-relation diagram.

For the remainder, I use only Telescope since I have just to specify my data and not to script the visualization taking into account the order of the instructions… So don’t change the interface of the existing API in order we can continue to use Telescope on top on Roassal.

If you want, I can show you the current stage of the visu (once again done in Telescope on top of Roassal) in order that you see on real data how uggly it is.

Cheers,
Anne

Do you have a screenshot showing the issue?

Yes please, some screenshots would help

Unfortunately making real graph layouts is really hard issue… I've wrote my bachelor thesis about this and didn't get very far; it's bit of a nightmare if you don't have good foundations. :'(

In any case, I wrote a simpler layout delegator in Roassal that delegates the layouting to graphviz and it works reasonably well, so I could probably add it to Roassal (you however need graphviz installed and it would add another dependency to Roassal, which I'm not so keen on).

Maybe also OGDF (http://ogdf.net/doku.php) could be used if you are ok with GPL… they have their own graph format so there could be some interaction.

I know. I tried but my mathematical background and my time were not enough. I got the research paper explaining the algorithm of Graphviz but even with that, it was very complex. However, since some tools (as graphviz) do it, we should have it.

how does that work? does it ask graphviz for the position of the nodes and then
recreate that in roassal?

Yes, I generate .dot file that describes the nodes I want the layout for (that includes the dimensions of it), and then the .dot file is passed to GraphViz… from there I parse the generated SVG file (they can also output other formats like txt, or xml) and move the Roassal nodes.

this would work the same as with graphviz as an additional dependency on ogdf, right?

GraphViz is good enough for generic graphs, but OGDF is well-founded and much more powerful layouting library. However C++ coding is required if one wants to use it.

My favorite improvement would not really be a Roassal feature
but would save me a lot of time:
I would like the configuration versions to stop depending on numbered
versions of outside dependencies (Glamour, Neo-JSON-Core)

Re: [Pharo-users] Re: Call for action for Roassal

Also personally I would like to have some more load options so I could load just the core of Roassal without all the chart and map builders and everything.

Hi!

I do not get this. Relying on the baseline is not enough?

Roassal is very simply packaged. Only 4 packages: Roassal, Trachel, Roassal2Spec, Roassal2GT. It is very unlikely that this list of package will grow (not until we have a Git integration at least). You can make your configuration directly point to these packages no?

Cheers,
Alexandre

#stable points to a numbered version, and that refers to numbered
versions of Glamour and Neo-JSON-Core. They always get out of sync.
the baseline is not specific enough

This is very cool. We will all benefit from this documentation.

One thing that I would still like to see fixed before the release is the edge building (this problem of not being able to properly specify random objects to be taken into account when building edges). Could we work on that?

Re: [Pharo-dev] Call for action for Roassal

Hi,

We discussed this before. Try to draw a hierarchy using classes and inheritance objects (so, without using the class to superclass navigation). Something like this:

view := RTMondrian new.
view nodes: classes.
view edges objects: inheritances; connectFrom: #superclass to: #subclass.
view layout tree.
view

It won’t work.

Re: [Pharo-dev] Re: Call for action for Roassal

Oh, but this has been in Roassal for many months (I have implemented since right after ESUG). You need to use #source:connectFrom:toAll:

Here is an example that randomly generate a graph and render it using this facility:

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

nbOfNodes := 40.
nbOfRandomEdges := 40.

nodes := 1 to: nbOfNodes.
edges := (1 to: nbOfRandomEdges)
collect: [ :notUsed | nodes atRandom -> {nodes atRandom . nodes atRandom} ].

b := RTMondrian new.

b shape circle color: (Color black alpha: 0.5).
b nodes: nodes.

b shape line color: (Color gray alpha: 0.3).
b edges
source: edges connectFrom: #key toAll: #value.

b layout force.
b

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Cheers,

Alexandre

Oh, I missed this one :). So, now I can refactor the code that is still using the RTEdge class side methods :).

Re: [Pharo-dev] Re: Call for action for Roassal

Hi Anne,

I've just added a Roassal plugin with the GraphViz-based layout.

Note that I had to hack it to work with RTMultiLine (it was originally designed for different lines which are currently not part of Roassal),

so it's possible there will be some issues.

You can load it (if you have latest Roassal installed) via the Roassal plugin menu,

or by executing the following

Metacello new

baseline: 'GraphVizLayout';

repository: 'github://peteruhnak/graphviz-layout:master/repository';

load

Then look at the class-side examples in RTGraphVizLayout.

Finally if you use this, you shouldn't move elements within the layout (because graphviz layout hard-codes the pathing)… we could probably change this in the future, but I am not sure how (ideally the layout would have to be recomputed, but that's expensive to do live),

So to summarize:

* you must have GraphViz installed in your system

* you must use RTMultiLine for lines (because only they support bending)

Let me know how it goes,

Peter

Oh, I missed this one :). So, now I can refactor the code that is still using the RTEdge class side methods :).

Great!

Thanks,
