GraphParserException from Grappa

hello, I have had this problem. It looks like an enoding problem for some characters. Any idea how to fix it? Thank you.

Limits to graph coordinates

Hi guys,

I'm using grappa and graphviz dot to generate new graphs.

The dot does a great job putting the nodes in the right place but now, I need to create limits in the coordinates generated.

For example it places the nodes in coordinates like (0,0), (450,200)...

I want is dot places nodes in the coordinate range (-180,-90)(180,90)

It is possible in attributes give this range to Dot?

Best regards
