Viewing reputation changes on Stack Overflow produces a nice graph which can be 'zoomed in' on to view more detailed reputation changes, for example. Is this using a library or is it custom written? If it's a library, which is it?

    Looks like highcharts on the reputation tab - highcharts.com

  • @Oliver: <s>have you tried to compare layout? They look slightly similar indeed, but the implementations are cardinally different. Highchart's one is svg-based, and SO's is pure html</s>. Oh wow, I haven't seen reputation page yet before :-S sorry, I was wrong

  • @zerkms The rep graph does use SVG elements, so you're partly right there.

Looks like highcharts because inspecting the DOM reveals stuff such as:

<svg ...>
  <clipPath id="highcharts-1">
  <g class="highcharts-grid" zIndex="1">

There are actually 2 reputation graphs,

I think the one you are referring is the the graph in reputation tab. The graph in reputation tab is rendered using highcharts in fact it is a master-detail type of chart.

While coming to the other one in the summary tab, its a html graph not a highcharts one.
