Is there a handy tool to create multiple html areas for a schematic map?

Question

HTML

I have a diagram. I am

redesigning an interactive map.
She is typical.

<img src="/images/map.png" class="map" usemap="#map">
<map name="map">
<area shape="poly" href="#" coords="437,757,436,774,...,437,740" data-room="101">
<area shape="poly" href="#" coords="439,706,438,713,...,439,699" data-room="102">
...
<area shape="poly" href="#" coords="439,706,438,713,...,439,699" data-room="XXX">
</map>

In this diagram, there are many rooms that will be assigned to the area accordingly. All these are polygons of various shapes and there are many of them.

That's the question. Whether there is a toolkit allowing to automate creation of similar heap of area objects? In order not to draw them individually with pens? Or ways to draw it all with minimal effort?
