Fork of Stylized Bar Chart
A stylized bar chart displays the populations of the world’s ten most populous countries, using data from the United Nations World Population Prospects 2019. The visualization is rendered as an SVG using React and D3 v5, with horizontal bars encoded using `scaleBand` and `scaleLinear`. Country labels appear on the left axis, and tooltips reveal exact population values formatted with D3’s `format` function, converting values like “G” to “B” for billions.
