Color Coding ontop of an existing image of a floorplan

I have a series of floorplans for my university. I know which students live in each room and have attributes (retention, gender, Greek life, race, GPA, major) for each student. I want to upload the existing graphic of the floorplan to a website and then make the floorplan interactive such that if people filter to see which rooms have students who dropped out, have GPA below 2.5, participate in Greek life etc, those rooms light up a certain color. I know the code can't be that complicated and I have experience with coding attributes in javascript but I'm wondering which language will be easiest to use for this specific project. Any help or suggestion will be appreciated!
