Sketching node and edge graphs by hand is a
quick and easy design process, not mired by clumsy interfaces or constrained by
the drag and drop tools. However hand drawn graphs can become convoluted as
more nodes and edges are added. The need to be able to rearrange the graph
quickly becomes apparent. Furthermore a formal beautified copy of the graph may
be required.
'Graph Layout' is a graphing program that
supports both low and high fidelity graph rendering. It runs on a Tablet PC to
take advantage of the pen. The user can create a graph by sketching or through
drag and drop interaction. Alterations made in either mode are reflected
in both the sketch and beautified versions of the graph.
'Graph Layout' uses optimization algorithms
to allow the transformation of tangled graphs into ones that are easy to
understand and follow. This required reflow and distribution of the digital ink
while keeping the graphs structure: nodes and edges are moved and stretched so
that they maintain a hand drawn appearance. Graph Layout gives the user the
best of both low and high fidelity design.
