I have a java swing application used to manage inventory, sales, cash flow, customers and other things of small business (generally newstands and similar business).
The application is offline, but I want to create in the website a dashboard where the users could see interesting charts and reports about its data. So probably I would create a mechanism in the offline application in order to be updating the database online day after day.
So my question is: does anyone know a good tool for developing dashboards? I don't need a complete BI tool because the users have 0% IT knowledge, I want something very simple, just like some graphics with different filters.
If possible I would prefer some free or cheap tools.
