It's easy to use, very flexible with many options for customization of its graphs/chats etc., it has multiple data sources support such as MS SQL Server Database or MySQL database; I have used this software in my work place where we are using Oracle DBMS but there was no issues related that i faced while working here! Nothing much like dislike about js charts apart from some minor bugs which were resolved by their customer care team after contacting them via live chat option available at bottom right corner side (which actually helped me alot).
For those who want quick analysis without having any programming skills then go through trial version first before you decide whether your requirements can be met otherwise stick only paid versions because they provide best results than free ones!! We need visual representation so our customers feel connected more closely when interacting over social media platforms hence providing better service delivery experience.
