Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects (e.g., points, lines or bars) contained in graphics. Visualization of data helps in finding specific information, like tracing data correlations by presenting the data in graphic form, and noticing how one set of data influences another.
