The Emergence of data mining can be considered as the result of the natural evolution of information technology In today's world large amount of data is flowing through our computer. This explosive growth of data is an outcome of computerization in our society and the advancement of data collection, storage tools and visualization. Data visualization is the use of graphical representations to exchange information with data. Data is visualized generally using different types of charts. Based on the medium of representation, we could categorize the visualization as one visualization in a stand-alone app like rapid miner tool and second is the visualization in a browser. In this paper we are mainly focusing on browser visualization using different types of charts. JavaScript is the language of the browser. There are different JavaScript libraries which help to render charts. Some of the popular JavaScript chart libraries are d3, high charts, nvd3 etc. Visualization in browsers can be further split into two using canvas and SVG (both are HTML5 features). Most of the chart libraries use SVG (Scalable Vector Graphics).
