I want to visualize a graph with Graphviz's layout using Zest. By executing
dot.exe -Tdot sample.dot, we can get the dot layout result which is also a
dot file, but with extra position information. The problem is the edges in
graphviz are generally curves and have several bend poiners. But I didn't
find how to achieve this goal by using Zest. I notice that there are some
method named setBendPointer() in Zest, but I don't know how to use it. Is
there anyone who know the answer?
