I need to create a line chart with a dual-Y axis. Currently, the secondary Y axis is available in Combo chart.
I did not see any open source code for combo chart or line chart available on github.
Can you share any references?

Yes, great question. Microsoft shared all their source code for custom visuals when they wer using the old model but I do not know of where we can get at the source code for visuals made using the old model.
I also suspect quite a few of the older, popular out-of-the-box visuals in Power BI are still in the older format as they work fine in backwards compatibility model.
You should also note that there is a custom utility for creating a custom axis at this url
If you learn to use the ChartUtils, that can assist you with creating axes in a Power BI visual.
