Please select the Lydgate works, by DIMEV title, from the dropdown to limit the visualization of the connections between them (crtl+click on PC, command+click on Mac). Click and drag a node to pin it on the canvas, and rightclick it to unpin it. Node labels can be hidden by clicking on the appropriate text in the legend. Note that it may take some time for the force-directed graph to appear, depending on the number of items chosen.
