This visualization presents a treemap of marketing funnel metrics across multiple channels, using nested rectangles to represent data from the economia_estados.csv file. The chart displays categories such as Twitter Impressions, Website Visits, and Cold Calling, with values shown for three different stages. The view can be toggled between a standard treemap layout and a cluster view using the checkbox control. SVG rectangles are rendered with opacity and labeled with category names and values. Hovering over a node triggers a custom tooltip (d3-tip) with detailed information, and the visualization includes smooth animated transitions when switching views. The color scheme and rectangular layout follow the classic treemap design, while the animation enhances the interactive experience of exploring hierarchical funnel data.
