Learn D3.js

This bar chart visualizes a static dataset of nine numeric values using SVG rectangles. The example demonstrates how to construct a basic chart with the D3.js v4 library. The code sets the SVG canvas dimensions, calculates bar widths based on the data array length, and uses `d3.select` and `selectAll` to append `rect` elements. Each bar’s height and y-position are derived from the data values, with a `transform` attribute translating each rectangle horizontally. The chart is contained within an HTML page with a light background.

Making a Bar Chart

This example shows a horizontal bar chart of population counts for major world regions, using a bar’s length to encode each region’s population value. The visualization renders as SVG rectangles positioned with a `d3.scaleBand` y-scale and sized with a `d3.scaleLinear` x-scale, both fed from a CSV file read via `d3.csv`. Data values are coerced to numbers before scaling, and the chart fills the full SVG dimensions defined in the HTML. React and D3 v5 work together, with selections and scales imported directly from the `d3` package.

Face with D3.js!

A yellow SVG face uses D3.js to animate its eyebrows downward and back, creating a subtle blinking or surprised effect. The face is composed of circles for the head and eyes, rectangles for the eyebrows, and a path for a smile, all drawn using vector graphics. The animation relies on `transition().duration(2000)` to move the eyebrow group's `transform` attribute between two vertical offsets, providing a simple looping motion within a React-styled D3 v5 environment.
