This animated scatter plot visualizes changes in average wages across countries over time, comparing each year’s values against the following year’s values in a sequence of transitions. The visualization cycles through data from 2000 to 2022, updating every three seconds. It uses D3.js v6 with SVG rendering, employing `d3.scaleLinear` for axes, `d3.scaleOrdinal` for country colors and year-based symbol shapes (circles, crosses, diamonds, and more), and `d3.axisBottom` and `d3.axisLeft` for grid lines. The code demonstrates a reusable chart pattern with configurable accessors and margins.
