javascript - how to describe or highlight certain points in charts and give hyperlink on that points -

i using protovis charts....i kind of new here... want want show area charts. , in want show few points different color or highlight point...and when click on point want open new page or show panel on same page...any idea how protovis? if not possible protovis can suggest other framework that?

i think you're looking this:

vis.add(pv.area)     .data(data)     .left(function(d) x(d.x))     .height(function(d) y(d.y))     .anchor("top").add(pv.dot)         .size(20)         .event("click", function (d) alert("clicked point " + this.index)); 

the important part .event("click", function (d) some_code()) bit. if you're using pure javascript, .event("click", function (d) { return some_code(); }).

here's working (albeit sloppy) example.
