Building standalone applications in VB.NET and Plotly.js

I need to build an application in VB.NET that will display line plots, scatter plots, and contour plots and will not be connected to a network of any kind. I wanted to use Plotly for this, but I don’t know how to proceed. I thought I could use plotly.js and could call it from VB.NET. When I looked into plotly.js, it said nodejs and npm were required, so I installed those. I saw some examples of running plotly.js in node, but they seem to run in an online mode and “call home”. Is there any way to run and call plotly locally?
