Graph card (without background) suggestion

I am looking for suggestions for an idea i had. I am not sure how to go about realizing it.

I think I could get close using mini-graph-card or apexcharts-card and card-mod to remove the card background and style the transparency.
Does anyone know of another custom card or have any ideas?

I am getting close.

Next, I am trying to move the temperature value down a bit.
