What is ChartChap
ChartChap is a free data visualization tool that enables non programmers to be able to use Google Charts in the projects and stories.
It also allows you to merge different datasets and create visualizations. Check out the demo here.
PHP version 5.4 or newer is recommended.
It should work on 5.2.4 as well, but we strongly advise you NOT to run such old versions of PHP, because of potential security and performance issues, as well as missing features.
ChartChap is based on CodeIgniter. You can check out the installation section of the CodeIgniter User Guide.
