I am just making the real time heatmap with d3_js.
But it dosen't change the data in real time.
And d3_js is difficult to me, I guess.
Could you tell me the easiest way to making the real time heatmap?

Please note - the "easiest way" depends on the frameworks / libraries you are most experienced with. We do not promote any specific front-end technology, so the choice if yours, as application developer, to make.

It updates the map with random values each 2 seconds, which should be replaced with data read from the target board. Here's how it looks:
