create graphs in Pdf using php inside cron job

Hello folks, We need script in which graph created inside PDF through PHP (Graph similar to attached PDF). Make sure we need to run this script as cron job so graph with pdf create on server side itself and similar graph will looks on HTML page. Data getting through database (mysql) or Json-encoded in PHP. Data will not going to be issue in whatever format you are going to retrieve. I need sample script/video with one graph (in which you need to just run script and direct pdf will going to be generated) for confirmation to allocate this project. Looking forward to see your proposal.
