This interactive visualization explores Amazon’s top 50 bestselling books from 2009 to 2019. It presents dual bar charts tracking average user ratings and book prices per year, alongside a scatterplot of individual books using logarithmic review counts, with circle size encoding price. Users select individual years via buttons to update the scatterplot. The code uses D3 v6 with SVG rendering, employing `d3.scaleBand`, `d3.scaleLinear`, `d3.scaleLog`, and mouse event handlers for tooltips, sourcing data from a Kaggle dataset.
