Is there any way to change how graphs are drawn in TortoiseHg?

Being used to how ClearCase draw graphs I find Mercurial's and TortoiseHg's way confusing at first glance.

This is how I'd like it to be represented: With static positions for branches. E.g. Maintenance branch to the left/right always and preferably in a straight line and not the current spaghetti curved branch it is now (see below link).

This is how it looks using the TortoiseHg Explorer. The graph is from a test repository. :-)

[edit]

Check out MacHg and how it draws the graphs. This is more in line of what I'd like to see myself.
