I created Interactive graphs using javascript and Amchart library. Interactive graphs show data points at particular points whenever the user moves the mouse pointer.
1) Download Amchart library http://www.amcharts.com/download/.
2) Add link of .js library in your html file.
To see output go to link:http://manpreet9112.github.io/JavascriptGraphs/curvedemo.html
Clone this repository https://github.com/manpreet9112/JavascriptGraphs and run its html file in browser.
