The ability to visualize the relationship between items, the weightage of the relationship and the flow often brings out the untold insights into limelight, which are otherwise not very evident. Simple numbers and basic charts won’t be enough to discover and tell such data stories. We need new visualization techniques for the complex world of relationship and Force-Directed Graph thrives to the forefront for such scenarios. This custom visual implements a D3 force layout diagram with curved paths. The thickness of the path represents the weight of the relationship between the nodes. Since the relationship and interconnection between large set of entities could be very complex, the visual positions the nodes in such a way that there are few crossings as possible, making the exploration experience easy, fun. The visual also produces the layout which is overall pleasing to the eyes for large data sets. Users can also adjust the layout manually by simply dragging the nodes around. Ideally you would need two dimensions and one measure (for the weightage) to use with this visual. But this also works just with a single column.

QUESTION
I'm trying to create a custom Force Directed Graph using the source code on Github (PowerBI-visuals-ForceGraph) and following the tutorial available at creating-a-custom-visual. Unfortunately, when I try to start the custom visual using the "pbiviz start" command in PowershellI I get an error stating "Invalid API version v2.3.0".
The "circlecard" example project used in the tutorial, which also uses API version v2.3.0 in it's pbiviz.json file, works just fine. So I'm clueless as to what's causing this error. I'm very new to trying out custom visuals on Power BI so any help with this is greatly appreciated.
Thanks in advance!
...ANSWER
Answered 2019-Jan-23 at 12:17PowerBI-visuals-ForceGraph visual was converted to use the new version of powerbi-visuals-tools@beta
If you installed the tools as global by command:
npm i powerbi-visuals-tools --global
and run pbiviz start
from global instance it will not work, because old tools doesn't support a new format of visual project.
npm run start
- start powerbi-visuals-tools from local instance
specified in package.json of the visual: https://github.com/Microsoft/PowerBI-visuals-ForceGraph/blob/master/package.json#L71
You need to install beta version of tool as global or run npm run start
to use the new tools
