This visualization shows the release dates of Marvel Cinematic Universe films plotted by their phase number, with phase values displayed on the y-axis and US release dates on the x-axis. The line chart connects each film in chronological order, revealing the spacing between releases across the franchise’s phases. Built with D3 v5, the code uses `scaleTime` and `scaleLinear` for the axes, `axisBottom` and `axisLeft` for tick rendering, and the `line` generator to create the path. Data is loaded from an external CSV using `d3.csv`, with SVG rendering for all elements.
