How to create a single value chart with trendline / sparkline for a KPI

[karthikv606]

I am working on creating an executive level dashboard and would like to create a single value visual that shows aggregate value in the single value card. In this same tile, I also want a sparkline of the KPI for the selected time range. 

I do not see an option on the edit chart section.

There is no such visualization available by default in looker, you can check marketplace and add suitable visual if you find it there, else you can go through Looker SDK to customize the visual.
