<p>We apply fillets — smoothing of sharp angles at the joints — between the connections and nodes of graph-like diagrams.</p> <p>In situations where the graph layout is constrained, e.g. Focus+Context views or views where the coordinates of the nodes are informative, fillets can clarify the relationships considerably without altering the layout.</p> <p>A visual search experiment supports our hypothesis that with fillets it is considerably easier to perceive node-connection structures.</p> <p>We discuss algorithms with different tradeoffs for flexibility and performance for rendering these connections in a single pass using OpenGL.</p>
