Interactive images

I need to include interactive maps for selling properties in my squarespace web pages. An example is below.

It would be good if information can come up as you hover over the various plots, but most importantly it should be possible to click on the plot to open a new tab with that plot's website content. 

How do I go about this in Squarespace? What is a good service to use to create code and importing this functionality?

Thanks, 

Sverre
