do get clear: You want a "area highlight module" so that the visitor of your page can highlight some areas? Right?
If so you/your developers will need to develop something by yourself. If you find a code/library or something similar online you could inject it into HubSpot with a custom module or just the plain files. You can search for "image hotspot code/library" in google. But there is no "ready-to-use" module/extension like this for hubspot
@Cory you could check the marketplace for a custom module. But if you want to keep that specific design you'll need a custom module designed.
If you know basic HTML/CSS, I'd recommend using an inline SVG and a bit of CSS to for the hover effects. The slightly more detailed version: start with this SVG of the united states, open it in a vector design app like Adobe Illustrator and add your circles and hover elements, export the SVG and copy and paste that code into the HTML of a new custom module. Finally, add the CSS to hide/show the hover boxes on hover of each circle.
My example no longer exists on that page, but I have another here (scroll down to see the map). It's not an actual map like google, just an internal map (flat graphic) for one of my employers developments.
Using HubDB to help streamline managing the data and to give a bit of interactivity to an otherwise boring graphic.
Thanks for your appreciation of my work @Kevin-C - makes it all worth it 😊
For anyone wanting more information, I'm happy to share how I pulled it off using HubDB / HubL / CSS / JS as it's evolved into a complex custom module to display all the different plot information using looping items , if statements and Pricing calculations using math operators to display a breakdown of a particular offer on that specific plot.
Sounds more tricky than it is. You just need to get your head around how HubDB / HubL works and the different functions available and you'll be on your way.
I believe that it accomplishes what you need, and rather than use the HubDB you can translate it into a custom module and modify the content directly from the content authoring tools.
