Hi
I have checked the document. I am interested in creating the Interactive HTML5 functionality as described in the document.
First, I can test existing libraries that might be suitable for creating the interactive Map along with custom functionality. The implementation of user account can be taken aside for now as main focus should be on chart generation and customization.
I have good experience of creating custom Interactive HTML charts (https://www.freelancer.com/projects/Graphic-Design/Build-Interactive-Graphing-Website-Based/). I have great experience with HTML, CSS, core PHP, MySQL databases, Javascript, Jquery and Bootstrap.
Looking forward to seeing your reply. Thanks.
Regards
Ahsan
