This interactive scatter plot visualizes population data across multiple dimensions, cycling through life expectancy, GDP per capita, population, and year as the x-axis every two seconds. Each circle represents a country, positioned by its selected x-value and GDP per capita on the y-axis. Built with D3 version 6.7.0, it uses d3.csv for loading, scaleLinear for axes, and axisLeft/axisBottom for rendering. The animation updates via setInterval, re-invoking the custom scatterPlot module to redraw circles and axes.
