Understanding the -Tplain output better
I am displaying the SVG rendered output from my graph in a window and am trying to implement tooltips and clickable actions when the user clicks on a node or edge label. The GUI library I am using (Qt) has QSvgWidget which does not show tooltips defined in the SVG file; therefore, I am doing a preliminary rendering in plain-text format which seems to give me a much better indication of where the elements are displayed on the screen.
However, if I have a text label such as "10001", the X coordinates seem to line up somewhere to the right of the first "1" and I'm not sure about the Y coordinates, although it is clear from the documentation that X,Y=0,0 is the lower left-hand corner of the window.
Should I add in some extra margin factor to the graph coordinates at the beginning of the plain output?
