We chose Tableau Desktop as our visualization tool because it is very simple to install and use. In order to use this tool, you need to have either Windows or Mac as it isn't available currently for any Linux distributions.
Get the executable/installer for Tableau Desktop from http://www.tableausoftware.com/products/desktop/download.
After the completion of download, execute the installer and follow the instructions to complete the setup.
As we are going to connect to MySQL, its connector also needs to be installed. You can go to http://www.tableausoftware.com/support/drivers and download and install the correct driver. If you are using any other data store instead of MySQL, you can install the relevant driver.
