Adding IBM custom visualization to Dashboard

[jahill938]

We are using Cognos Analytics 11.1.7.
Our client wants to add the custom gas gauge visualization from https://community.ibm.com/accelerators/catalog/content/Gas-gauge
I downloaded the zip file and uploaded it to Cognos. I also uploaded the sample .xlsx file for testing purposes.
The custom visualizations shows up as expected.
I tried adding the visualization to a dashboard but get the following error:

Script error for: https://d3js.org/d3.v5.min.js
http://requirejs.org/docs/errors.html#scripterror

They also want https://community.ibm.com/accelerators/catalog/content/Overlay-bar and I get the same error trying to use it as well
Not sure what I'm doing wrong or if there is some kind of compatibility issue.
