Given a agent based model (using Agents.jl) of agents on a 2d grid with values between 0-10 (continuous) is it possible to produce a heatmap using `abmplot`? (each agent has a Float param) If so what is a straightforward approach for that? Is there an approach which does not require an observable?

`abmplot` mostly only deals with the actual plotting, so you as a user still have to take care of the data that should be plotted. If you want to create a _simple_ heatmap, have a look at the [Preplot related subsection in the docs](https://juliadynamics.github.io/Agents.jl/stable/examples/agents_visualizations/#Agents.abmplot), specifically at the `heatarray` kwarg. If you fancy a more fancy heatmap, you can also use the `heatkwargs` kwarg to style it. And finally, if you want something a lot more involved, you can also just plot a `heatmap` plot yourself over/under the `abmplot` (but that would require basic knowledge of observables and the Makie ecosystem, I suppose).

Are there any examples to showcase how this can be done for heatmaps of agent properties using the different approaches which you recommend? eg. " `heatkwargs = NamedTuple()` : Keywords given to `Makie.heatmap` function if `heatarray` is not nothing"

Sure thing: All the [heatmap examples listed in the Makie docs](https://docs.makie.org/stable/examples/plotting_functions/heatmap/) can be applied in the same way to the `abmplot` recipe via the `heatkwargs` keyword argument.

The `xs`, `ys`, and `zs` are determined by the `heatarray` input to `abmplot`. The `zs` are likely what you want to derive from your agent properties.
