For your application you probably don't want to have the whole Squiggle browser running. Instead you can create your own JFrame and stick a JSVGCanvas inside it. The JSVGCanvas is the main SVG rendering component that Squiggle uses. http://xml.apache.org/batik/svgcanvas.html > 2, if the svg graph is only slightly changed, e.g. change the color of > only one arc, do i have to regenerate a new svg file and restart the > browser again? is there a faster way? You can just update the document that is currently being displayed by the JSVGCanvas using DOM calls. http://xml.apache.org/batik/domapi.html > p.s. is there an svg tag showing directed arcs (with arrows)? There is a 'line' element for straight lines, or 'path' for more complex paths, and you can use the marker-end property to give it an arrow head.
