Visualization API | drupal.org
Visualization is a module for Drupal 7.x that provides a solid and easy accessible way to visualize data. It provides a theme hook that takes a data array and some options and will then render a chart in-place. It also provides a Views Display plugin so that users can easily visualize data retrieved through Views. The different charting libraries are pluggable through the CTools Plugin system; the module provides an implementation for the Google Visualization API and Highcharts.
