We recently added new visualizations to mbeddr. These new visualizations are based on PlantUML, a textual language for describing UML diagrams, plus a renderer that generates the diagram itself (partially based on Graphviz). We’ve built our own SVG-based viewer, integrated into MPS, so we can use click-to-go-to-editor from within the picture. It is easy to build custom visualizations simply by implementing an interface and overriding a method that generates the PlantUML input text. The rest is automated.
PlantUML is highly recommended: works well, easy to use, and when we encountered a problem, we got a reply to our question quickly, and within a few days, there was a new version that fixed the problem. In other words: PlantUML is actively maintained and the community is alive!

Hi Markus,
I´ve downloaded the lates zip-version of mbeddr (1081).
I run it together with ver. 2.5.3 of MPS.
I´ve downloaded plantuml.jar and just putted it into a location that is in the path.
\Graphviz228\bin is already in the path.
What do I need to do to get the “Visualize” menu point
to be able to run PlantUML. Is any Language requiered ?
regards,
Rudi
Hi RUdi,
* you don’t need to install plantuml separately. It is bundled.
Only Graphviz must be installed separately.
* You just need mbeddr.core, and you get the visualization menu
automatically for the respective concepts: modules, components,
state machines.
I just reverified this with out VM installation.

Hi Markus,
now I can start it (in model: com.mbeddr.tutorial), but get following error in green :
“Dot executable : null
cannot find Graphiz. You should try…….
java -jar plantuml.jar -testdot”
1. checked that Graphiz is still in path: OK.
2. I tried to run “java -jar plantuml.jar -testdot” on cmd line from mbeddr-core where plantuml is stored.
–> Display-result:
The environment variable GRAPHVIZ_DOT has not been set
Dot executable is null
Error: No dot executable found
Error: only sequence diagrams will be generated
My system is Windows 7.
Any idea?
Rudi
> Any idea?
Yes. You have to make the GRAPHVIZ_DOT environment variable point to the dot.exe executable (it does say so in the User Guide :-)).
Also, 2.28 may not work, we use 2.30 here.
Markus
Ok, works now.
Thanks Markus !
