Answer: Sankey

A Sankey diagram (E) is specifically designed to visualize flow and movement between different stages or nodes, making it ideal for showing user flow through a website. It effectively displays the quantity of users moving from one page or step to another, highlighting paths, drop-offs, and conversions. The community discussion shows 100% consensus on E, with upvoted confirmation that it's correct. Other options are less suitable: Heatmap (A) shows density or intensity patterns, Choropleth (B) displays geographical data, Word Cloud (C) visualizes text frequency, and Pivot Table (D) is a data summarization tool, not a flow visualization.
