Density-contour maps on Vega-lite-api

[Smitha H]

Hi,

I have built a scatter plot using Vega-lite-api ( javascript) and I have way too many points overlapping .. so would like to do a density-contour plot .. can you please point me to some Vega-lite-api examples of using density-contour. I found an example here https://vega.github.io/editor/#/edited  but this in Vega format .. I would like to do this using javascript ( Vega-lite-api).. any examples will be great.

Thanks so much,

Smitha
