I (plan to) have an image on my website with a graph.

3 points inside the graph a marked with a big dot. next to those dots there should be buttons (phase 1, phase 2, phase 3). ideally there should be a line between the dot and the button - the user should easily identify the corresponding button to the specific dot.

if mouseover on dot, line or button all three: dot, line and button should change the color. in case of click on one of the three elements: follow the link. all should be ON the graph / image not next to it.

I'm pretty new in odoo but i've some skills writing software. Hopefully someone is able to provide some information how to realize.

Thanks a lot

Peter
