        If a StringAttribute named "_color", or a ColorAttribute is set then use that color to draw the line.

        If the attribute is named "_color", then the value of the attribute is passed to SVGUtilities.getColor(String), which has accepts the following format: If the first character is "#" or "0", then the value of the attribute is expected to be in a format suitable for java.awt.Color.decode(). Otherwise, the value of the attribute is passed to checked against a list of color names defined in SVGUtilities, if the color name is not found, then the value of the attribute is passed to java.awt.Color.getColor(String) and if there is no match, then the color black is used.

        If the attribute is an instance of ColorAttribute, then the javax.swing.JColorChooser gui will be offered as a way to edit the color.

        If the StringAttribute "_explanation" of the edge is set then use it to set the tooltip.
