Build complex charts that 'reloads' based on complex parameter selection

I have a database of 20 columns and 4000 rows. I need to get a series of tornado and scatter plot charts as and when user tweaks various parameters. Since the idea is a bit tough to understand, I can give you the queries too and in what sequnce they need to be executed. But the main help I need is to generate tornado graphs, scatter plots, etc from data obtained via php / mysql and plot them on a browser.. I have already a basic user management for users to login, but i need some help in makign the site neat and clean
