Data Visualization with D3

This example shows a bar chart of population values for a list of countries, with each bar’s length scaled linearly and countries arranged along a categorical band scale. It uses D3 v5 with SVG rendering, applying `d3.scaleLinear` and `d3.scaleBand` to map data to positions, and `d3.axisLeft` and `d3.axisBottom` for the axes. Data is loaded from a CSV file via `d3.csv`, and population figures are parsed and multiplied before rendering.

Data Visualization with D3

This example displays a bar chart of categorical data from a CSV file, comparing numeric values across named categories. The visualization uses an SVG canvas with axes, mapping the data's numeric values to horizontal bar lengths and category names to vertical positions. The implementation relies on D3 v5 utilities for data loading via `d3.csv`, linear scaling with `scaleLinear`, and axis generation with `axisLeft` and `axisBottom`, while the chart is rendered as SVG rectangles within a React-based HTML page.
