Image Map Apps

Hi folks, fairly new to Devops in my new role. Previously been an Atlassian guy. I'm a big fan of using wiki for documentation. One of the things Atlassian had was you could buy apps to create image maps. Useful for things like software architecture so you could click an area to open up specific information on another page related to that area. I am struggling to find any apps in Azure marketplace though, anyone got any they recommend?
