Graphics widget

We can get a beautiful graph by following this flow, but there is no option to apply the client filtering

Long term data | Graphics | Pick “Today”

I wish to build a page (/var/www/html/custom.php) which plots few graphs, each representing a given client (or group of clients).

It would be great if we can have some UI visualizer widget, which can be easily IFRAME-ed

Many clients:
PiHOLE_URL/admin/db_graph_block.php?token=XXX&last=24h&client=192.168.1.22&client=192.168.1.101

Just a thought!
