Heatmap using GPU.js
In this notebook, we use the Javascript framework GPU.js to compile custom WebGL shaders to render and animate the heatmap together with normal Wolfram Language graphics primitives.
All dependencies are kept within this notebook and do not require installation or compilation.
Building common module (optional)
We build a simple module, which will hook up a CommonJS module to a global variable so that we can continue experimenting with compute shader code without needing to rebuild the whole thing.

Compute shaders
Here we use GPU.js to write a compute shader in Javascript, which use privded array of 2D points and renders their density to a canvas. We shall support the possibillity to update the image in real-time and use PlotRange, ImageSize parameters similar to Plot function

Output form
To display the heatmap, we need to define an output form in Wolfram Language, that will use Javascript to render the widget
HeatMap /: MakeBoxes[h_HeatMap, StandardForm] := With[{}, ViewBox[h, h] ] HeatMap /: MakeBoxes[h_HeatMap, StandardForm] := With[{ o = CreateFrontEndObject[h] }, MakeBoxes[o, StandardForm] ] /; ByteCount[h] > 1024 Options[HeatMap] = {ImageSize->{320, 240}, PlotRange->{{-1,1}, {-1,1}}};
Test
Create a bunch of points and render it
HeatMap[Exp[-Norm[#]]# &/@ RandomReal[{-Pi,Pi}, {30,2}]]

Integration with Graphics
Using basic Inset we can place it under any graphics
range = {{-1,1}, {-1,1}}/2.0; dataset = Exp[-Norm[#]]# &/@ RandomReal[{-Pi,Pi}, {50,2}]; Graphics[{ ColorData[97][4], PointSize[0.03], Inset[ HeatMap[dataset, 4000, PlotRange->range, ImageSize->{344,244}], (range[[All,1]]+range[[All,2]])/2.0 ], Point[dataset] }, PlotRange->range, ImageSize->{420,320}, ImagePadding->30, Frame->True, Axes->True ]

Make it dynamic
We should take a full advantage of the WebGL and perform smooth animation of the data points. For this we define helper function to guide our points though the calculated path
fixedPoint[args__, maxN_:Infinity] := NestWhile[Function[input, With[{ pos = input[[1]], target = input[[2]], velocity = input[[3]], iteration = input[[4]] }, { pos + 0.01 velocity, target, velocity 0.9 + 0.1 (Normalize /@ ( target - pos)), iteration + 1 }] ], {args}, (Max[Abs[#[[1]]-#[[2]]]]>0.1 && #[[4]] <= maxN)&][[{1,4}]]
Now we generate the data, find the number of interations steps until all points converge the target positions and assign a slider to control the process
(* input data *) range = {{-1,1}, {-1,1}}; points = RandomPoint[RegionDifference[Disk[{0,0}, 0.6], Disk[{0,0}, 0.5]], 100]; (* place points outside the viewport *) offscreenPos = With[{corners = range // Transpose}, RandomPoint[ RegionDifference[ Rectangle @@ (2 corners), Rectangle @@ corners ], Length[points] ] ]; (* procedurally animate each particle *) With[{ vel = 0.1 RandomReal[{-1,1}, {Length[points], 2}], target = points }, points = offscreenPos; With[{ maxIterations = fixedPoint[offscreenPos, target, vel, 0, Infinity][[2]] }, EventHandler[InputRange[0, maxIterations, 1, 0], Function[i, points = fixedPoint[offscreenPos, target, vel, 0, i][[1]] ]] ] ] (* render *) Graphics[{ ColorData[97][4], PointSize[0.03], Inset[ HeatMap[points // Offload, 4000, PlotRange->range, ImageSize->{344,244}], (range[[All,1]]+range[[All,2]])/2.0 ], Point[points // Offload] }, PlotRange->range, ImageSize->{420,320}, ImagePadding->30, Frame->True, Axes->True, TransitionType->None, "Control"->False ]
