jsvnstat – interactive network traffic analysis

Update: Version 2.0 is here!

jsvnstat is a web frontend for vnstat. It is largely based on javascript, so you can easily switch views without reloading the entire page. The graph is interactive, just hover over a datapoint to see what I’m talking about.
You can switch between line- and bar-graphs. You can also change settings such as decimal numbers in the settings.php file.
