Spacing between bricks in a heatmap

I’m trying to add spaces between bricks in my plotly heatmap to make it look like the above image. The closest workaround I’ve found to solving this is to implement something like http://codepen.io/etpinard/pen/dMQrKN. Would it be possible to add a padding field to the heatmap api that will specify padding for bottom, left, top and right of each heatmap brick?

@etpinard 👍 to horizontal and vertical.

@CalvinFernandez looks great! PR away 🚀

One thing though, when you’ll make your PR, the image tests fail on CI because your newly added heatmap_brick_padding.json mock has no corresponding baseline image. If you’re feeling adventurous, you can try generate that baseline image locally using our image-test docker container. See docs here. If you find that too much of a pain, I’ll upload the CI artefact to the PR thread.
