Hi @mspector13 - an issue for you, if you are up for it. As a way of checking how good the documentation is, I was wondering if you could please fix some minor issues in the CINMS and OCNMS infographics. So, the relevant section of the documentation would be image creation. Any suggestions on the documentation would be welcomed.

Here are the OCNMS infographic issues:

The highlighting functionality in the OCNMS images is not working properly in a few instances because the clickable element is a pixel-based image and not a vector element. You can still click on these elements, but they won't highlight as the highlighting code has no idea what to do with pixel-based things. These pixel-based elements should be replaced with vectors. These instances are:

• Kelp Forest: contaminants
• Pelagic: contaminants
• Pelagic: southern resident killer whales
• Sandy beach: contaminants

Here is the CINMS infographic issue:

• In the Deep Seafloor infographic, there is no icon for Biodiversity.
