Script to reproduce the example above: Based on my original Problem ( C3/D3 pie legend format / label overlap ) I have attempted to apply a bugfix originally created for flot to the C3 piechart. append("svg") . Offset is computed from [top, left]. getCTM() Returns a DOMMatrix representing the matrix that transforms the current element's coordinate system to its SVG viewport's I'm trying to create DAGs with dagre-d3. getBBox(); // return Where's getBBox -- a method of SVGGraphicsElement -- when accessed from within a selection? Well, if the selection doesn't exist, then there isn't a bounding box to get. I'm trying to add a rect element behind text with d3 to simulate background-color which doesn't exist for d3 text elements.
