It's easy for me as developer using it because I don't need any other skill or tools like Excel etc., only Java skills are required which i have! Nothing dislike about this software but if there should be something then maybe they could improve its look & feel by adding some more colors so we can easily identify our business values from them without looking at their names too much? Also when user select multiple check boxes (like color) all of those will show up while selecting one value shows nothing!! So we had trouble tracking changes during selection process. This problem was solved after switching back my default browser(Firefox). Its really worth trying out since everything needed just comes along within 1 click itself unlike excel where many steps involved even though simple things such us formatting needs lots of time taken. We've been able solve data visualization problems quickly thanks to these types of tool and also helped reducing workloads among developers who were handling visualizations tasks.
