Hi @Salil. These are not pie charts, but rather more of “infographics”, or perhaps “soccer ball” charts. The standard ARC mark used by Vega-Lite creates a “slice” rather than a polygon, so I think you’re out-of-luck with Vega-Lite (I wouldn’t be surprised if Vega could be leveraged, but I can’t comment as I haven’t explored Vega much).
