Flash graphics with Open Flash Chart
You can have flash graphics for databases' size, tablespaces's size and tables's size. To activate the graphs, you need to download Open Flash Chart PHP library from its website. Then, you have to extract four files: open_flash_chart_object.php, open-flash-chart.php, open-flash-chart.swf, and swfobject.js. pgsnap needs to find these files in the external directory.
