I like that it's easy to use since i'm not familiar with R or any statistical software packages yet (i need more time). Also you can save graphs as images which makes me feel comfortable about sharing them online without worrying if anything will be lost in translation from one format/software package into another - great! It also allows us at my work place easily share data sets we are working off of so everyone has access when they want too see what others have done thus far before continuing their own tasks independently.- The colors used aren't always very intuitive but this isn;t really an issue anymore now because there was no color scheme available initially- Sometimes its hard figuring out exactly where certain features appear after zooming way up close though sometimes things just seem blurry even thought zoom level appears correct-. Not much else comes across here other than being able get some basic information quickly using free open source graphing toolkit provided by web browsers such Google.
