Fork of Let's make a face with D3.js!

This example uses D3.js to build a smiley face directly in SVG, with animated eyebrows that move up and down in a repeated cycle. It demonstrates basic DOM manipulation by creating circles for the eyes and face, rectangles for the eyebrows, and an arc path for the mouth using D3’s `arc()` helper. The animation relies on chained `transition().duration()` calls to shift the eyebrows’ vertical position. The code explicitly imports `select` and `arc` from D3 and renders everything within a 960x500 SVG canvas.

Scatter Plot

This scatter plot displays the number of occurrences for each nation, with country names on the y-axis and values on the x-axis. The visualization uses D3 v6 with SVG rendering, importing `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `format` from D3. Data is loaded from a local CSV file, with values multiplied by 1000. Rectangles represent each country, scaled proportionally to their numeric values, with formatted tick labels using `format('~s')` to abbreviate large numbers.

This example shows a horizontal bar chart of the number of cases across several countries, with the data loaded from a CSV file. The bars display values in a compact format using D3's `format` with the `~s` specifier. The chart uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis categories, and `d3.axisLeft` and `d3.axisBottom` for the axes, all rendered as SVG. The code also applies margins, a title, and axis labels, with styling defined in a separate CSS file.

CSV

This example renders a yellow smiley face using React and D3.js, with SVG circles for the face and eyes and a D3 arc generator for the mouth. The shape is centered in a 960-by-500 viewport, with a black stroke around the yellow background circle. It demonstrates how React components integrate with D3’s `arc` API to build static geometric visuals from hardcoded dimensions. The mouth path is created via `arc()` with specified inner and outer radii and angular extents, while the eyes and background are plain SVG elements.

Fork of D3 Starter

This example demonstrates the simplest possible D3 version 6 setup by rendering the text “Hello D3 version 6” directly onto a blank page. The visualization uses the `d3.select` API to target the body element and replace its content with the string, working with the `d3.v6.min.js` library. The page’s styling, centered and scaled to 13em font size, makes the greeting visually prominent. No data is loaded or transformed; the visualization serves as a clean baseline for starting D3 projects.
