The legend on Stack Exchange Data Explorer (SEDE), keeps going on, below the bottom of the page, on a white background, breaking the page (I've cropped this out to keep the page from being needlessly long).
An example can be found here
Ways this could be fixed
Option to extract the legend to a table
This would allow for multiple columns
It could stay in the same space without breaking the page
The option to remove the legend
This would allow for a mode that is nearer to a line graph, with no legend
