title: create a custom visual for funnel chart powerbi
body: <p>I need to create a custom visual for Funnel Chart similar to <a href="https://docs.microsoft.com/en-us/power-bi/developer/visuals/develop-circle-card" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/power-bi/developer/visuals/develop-circle-card</a>.
  I want the functionality of increasing it decreasing the chart in the similar way as circle card. I have no knowledge of d3 or java script. There seem to be no code related to funnel chart for custom visual which I can refer to. Does anyone have any idea how can I proceed?
  Thanks in advance.</p>
