I want to build a website that displays data from an external databases. The data must be displayed in the form of charts, because charts are more expressive. I've never developed any websites yet, can anyone give me some advice about existing web frameworks and what are the advantages and disadvantages of them?
Which framework should I choose? The data are stored in an SQL Server. Because new data report types might be required in the future, the framework must be easy to modify and expand.
