This animated visualization compares the relative heights of five notable structures, from the Burj Khalifa to an average ten-story building, using circles scaled proportionally to each structure’s height in meters. Rendered on a black background with labeled white text, the circles animate in sequentially with a slow fade, while updates and exits use faster transitions. The code leverages D3’s `transition` and `easeLinear` APIs, along with `select` and data joins, to drive the animation. Data originates from Kaggle’s World Tallest Buildings dataset and Wikipedia’s Prudential Center page.
