Out-of-line Links Objects dont carry a link on them, all linking is handled outside of the graphics file WebCGM: –one event handler for all objects (not fully standardized yet) –straightforward implementation SVG: –Objects are clickable only if there is a link attached to them –Alternative: assign an event handler to each object on the illustration – impractical for large scale projects with thousands of objects –Alternative 2: lots of scripting on the outside
