CodeIgniter for Data Analytics Reporting

Hello friends,
We are a core PHP developer using Bootstrap/JQuery/AJAX etc but never used any development framework. We have built a number of applications so have a good experience in core PHP. We do write elegant code that contains usable modules. However, we know we need to move forward and adapt a more modern framework which can make our apps more scalable and take less time to develop.
We are evaluating frameworks to start with. But we also have a clear requirement. The application will deal with large volumes of data and will need to display various dashboards and reports. We are considering Kool Reports for this but unsure whether Code Ignitor is the right platform for this. Thei application will be a front end for our customers to view various analytics reports.
Any guidance or help shall be appreciated.
Thank you,
Sharad

The sample code in "With Codeigniter Database Query" is for CI3, 
but you probably can use with CI4 with the small modification.
