This example plots global economic growth using a scatter plot of GDP per capita against time. Each small blue circle represents a single country's GDP value for a given year. The visualization uses a logarithmic y-axis scale to handle the wide range of data values, revealing trends across nations from 1800 to 2100. The code combines React's state management with D3.js v7, using `scaleLog` for the axis, `scaleLinear` for time, and `csvParse` to transform the loaded Gapminder dataset into a long format for plotting.
