Want to build Room Temperature Heatmap Plugin

Hi, hope everyone is doing great. we have multiple sensors reporting data to our influxdb database. this includes temperature, barometric pressure, humidity, and air quality. For now, grafana has been a great help to visualize data from these sensors. Now we are in a situation and need help. we want to visualize temperature data from sensors to floorplan as a heat map overlay. we have used SVG plugins but those are not working as we expected.

here is SVG plugin panel

here is what we want to achieve.

is it possible with grafana? if yes how. can we develop a custom plugin to display such visualization? any help will be highly appreciated.

here is link to a reference article.

is there any way we can achieve it without developing a custom plugin?
