This visualization displays population growth data for five countries from 2012 to 2017, presenting each country’s initial population alongside yearly growth values. The code uses D3 v5 selection methods to log the structured dataset to the console, where each entry contains a country name, base population, and nested growth object. The d3.v5 library is imported via ES module syntax, specifically leveraging the `select` function, though the primary interaction occurs through JavaScript’s native `console.log` for data inspection. The visualization relies on a hardcoded array rather than external data sources, with styling handled by a separate stylesheet that sets a dark background and large Ubuntu typography.
