In `PlotlyJS`, the relevant attributes (see [Single-page reference in Julia](https://plotly.com/julia/reference/)) for fixing the aspect ratio are `scaleanchor`, `scaleratio` and (not allowed simultaneously with these) `matches`:

```julia
p = Plot([heatmap(x=x, y=y, z=f, colorscale=colors.plasma,colorbar_thickness=24), 
               scatter(x=0.5*cos.(t), y=0.5*sin.(t), mode="lines",
                       line_width=2, line_color="black")],
               Layout(width=600, height=320, yaxis_scaleanchor="x", yaxis_scaleratio=1,
                      xaxis_range=[-2,2], yaxis_range=[-1,1]))

```
