Generate Your Visualized Data

You know that if are visualized  your data in html then you use some specific CSS code and these are width/height  for different -different part of your data, but you have visualized your data without css ? that is possible by using D3.js . D3.js is java-script library that uses digital data to drive the creation and control of dynamic and interactive graphical forms which run in web browsers. Here d3 means just for data-driven documents.

To create chart i am use mydata.json file and for connecting to file i am use the d3.json . where .json show the file extension . if you can use csv file then use d3.csv function .
