<p>Labels of edges can be aligned to edges in various ways.</p>
|
|
<p>Text-alignment within node labels can be 'left' or 'center', other font alignments not implemented.</p>
|
|
<p>Label alignment (placement of label "box") for nodes (top, bottom, left, right, inside) is
|
|
planned but not in vis yet.</p>
|
|
<p>The click event is captured and displayed to illustrate how the clicking on labels works.
|
|
You can drag the nodes over each other to see how this influences the click event values.
