scan image

The Scan Image organizes Web pages from most negative to most positive in terms of user satisfaction.

benefits

+	determines the size and extent of problems on a website
+	graphs the "geography" of the website - i.e. Web users rate satisfaction differently from one area of the website to another
+	prioritizes page-level analysis by identifying poorest (and best) performing pages

features

+	each line on the graph represents a page of the website: green lines represent Web pages that have been rated positively, black lines represent Web pages that have been rated neutrally and red lines represent Web pages that have been rated negatively
+	number of ratings is indicated by the length of the line
+	bimodal distributions are highlighted to prevent misinterpretations of the data
+	graph zooms in and out to facilitate the analysis of heavy and light trafficked pages
