How to make bitmap editor (plot a family tree)

Yes.

An initial attempt to parse some of the data:

I was able to extract the pairs of numbers easily enough (from experience).
The remaining data may be a challenge.

If a visual examination (look for patterns) allows manual parsing then you may be able to write code to parse it. This very much depends on the data provided.

Is the data you provided (you have a picture a few posts up) generated from another source? The original data set (not always available) may be easier to work with.

Have fun!
