I created a tool on the Django admin for positioning hotspots on an image. Hotspots on an image are points that can be clicked which will then display a pop-up with more information. I created this because we had maybe 50+ hotspots to place. Without the tool it would be a manual job, figuring out exactly where to place them. With the tool, all we had to do was drag and drop the hotspots on the image.
I wasn’t involved with the front-end except for a few minor CSS fixes. I was only involved in working on the Django admin tool for placing the hotspots and assigning the extra information they needed to display.
Unfortunately, I didn’t take a screenshot of the tool (and I probably wouldn’t be allowed to share it) so I created a mockup instead. I also started work on a free/open source implementation, it’s called jquery-hotspot-placement.
