Making a Bar Chart
This bar chart displays movie budgets against movie titles, with color intensity and hover interactions revealing each film’s IMDb score. A clickable green circle toggles an animation that collapses and expands all bar widths using `d3.transition` with a 1000ms duration, changing the circle’s fill from green to red or blue. The visualization is rendered as SVG using D3 v5, employing `d3.scaleLinear` for the x-axis and color, `d3.scaleBand` for the y-axis, and `d3.axisLeft`/`d3.axisBottom` for ticks. Data comes from a local CSV file listing budgets in dollars and IMDb scores.
