Canvas scatterplot DC V3

[icoert]

I like the idea of using a scatterplot with larger datasets, but the performance is affected and that's why a canvas scatterplot is necessary. This issue was disscused before. For now, the implementetion of canvas scatterplot works only with DC V2, which uses D3 V3. I would really like to port it to DC V3 with D3 V5. Any help?

Here are the new examples:
