This bar chart displays Data Science Salaries from 2020 to 2024, sourced from a CSV file in a GitHub repository. The visualization uses D3 v5 to render an SVG with a blue bar for each year's average salary. It includes an interactive tooltip that appears on mouseover, showing the specific year and salary value. The chart features rotated x-axis labels and styled axes, with the bars animated via D3's transition methods for the tooltip opacity.
