A bar chart displays the number of Netflix movies released per year, with a hover effect highlighting individual bars. The visualization filters a CSV dataset to movies only, counts titles by release year using `d3.rollup`, and renders the result as an SVG with `d3.scaleBand` and `d3.scaleLinear`. Axis ticks are thinned via `tickValues` to avoid crowding, and a summary line reports the total movie count. The code uses `d3.csv` to load data from a GitHub Gist and D3 v7 for all chart construction.
