A graphical summary that helps to figure out how viewers are engaged with a specific video is called a Video Heatmap. Unlike heatmaps used in website analytics, which highlight different areas of a web page depending on the click-through rate, a video heatmap aggregates stats from every viewing session and calculates an average engagement rate (also known as watch rate) throughout the entire video. Depending on the platform, a video hitmap can be represented in a form of a graph or a colored timeline.
