Thanks! Sorry for the late reply. I'm using flot charts [1] for the big traffic graph and peity [2] for the smaller ones. Apart from that, there are some other good options like morris.js [3], Chart.js [4], flotr2 [5], xCharts [6] and sparklines [7]. There are more if you search for them but I've used the ones I mentioned in the template. Added more screenshots of the charts pages. [8] [9] [10] [11]
