ao3

A scatterplot-like visualization maps AO3 fanworks from a 2020 CSV dataset, with each dot representing a work positioned by its publication count and hit popularity. The SVG rendering uses D3 v3's `d3.nest` to group works by rating category, arranging them in grid-like clusters, while `d3.scaleLinear` maps hit counts to dot opacity. Drop shadows are applied via SVG filters with `feGaussianBlur` and `feFlood`, and the React-free code loads data asynchronously with `d3.csv`.

Scatter Plot with Menus

This scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, displaying cars as red circles. Users select which numeric columns map to the x- and y-axes via dropdown menus built with a custom `dropdownMenu` function. The chart updates through D3 v5, using `scaleLinear`, `axisBottom`, and `axisLeft` for scales and axes, with animated circle transitions (`transition().duration(2000)`) as new data is rendered.

Let's make a face with D3.js!

This example builds a cartoon face from basic SVG shapes—a yellow circle, two eyes, rectangular eyebrows, and an arc-based mouth—all positioned relative to the center of the viewport. The code uses D3.js v5's `select` and `arc` APIs to construct the geometry, and SVG `transition().duration()` to animate the eyebrows downward by 50 pixels and back over two seconds. The rendering approach is fully declarative, with the face components grouped and transformed together, and all coordinates computed from the SVG element's width and height attributes.

Let's make a face with D3.js!

A smiling cartoon face is drawn with SVG shapes using D3.js v5, featuring animated eyebrows that move downward and back upward over two seconds. The face uses a yellow circle, black stroke, and an arc-generated mouth with `d3.arc`. Code imports `select` and `arc` from D3, applying chained `transition().duration()` calls to animate the eyebrow group’s transform. React is noted in metadata, though the example runs as a standalone HTML page with a static SVG canvas.

Let's make a face with D3.js!

This example shows a simple cartoon face built with D3.js v5 and React, rendered as SVG with animated eyebrows. It uses `d3.select` and `d3.arc` to create the face shape, eyes, and mouth, while `transition().duration()` animates the eyebrows up and down repeatedly. The face is centered using SVG group transforms, with fixed pixel offsets for eye spacing and brow placement. No external data is used; all geometry is defined directly in code.

Let's make a face with D3.js!

A simple cartoon face built from SVG primitives appears on a yellow circular head with black outlines, featuring two eyes, movable eyebrows, and a mouth drawn as an arc path. D3 selections and transitions animate the eyebrow group’s vertical position over two seconds, first lowering and then raising it. The code imports `select` and `arc` from D3 v5, uses SVG circles, rectangles, and paths, and runs within a React-created bundle on a bare HTML page.

Interactive Color Legend

This interactive scatter plot visualizes the Iris dataset, mapping petal length and sepal width with a color-coded legend for species. Built with React and D3 v5, it uses `scaleLinear` for axes and `scaleOrdinal` for color mapping, rendering SVG circles. Hovering over a legend item filters the marks via `onMouseEnter` and `onMouseOut`, fading non-matching points to a specified opacity. The axes are generated with custom `AxisBottom` and `AxisLeft` components, and the data is loaded asynchronously using `csv` from `useData`.

Shapes and Colors with SVG and CSS

This example demonstrates a blank SVG canvas with a linked stylesheet, using D3 v5 to log the library to the console. It shows the basic setup for an SVG-based visualization, where the document structure contains minimal elements and the stylesheet applies global body styling. The code relies on the `d3` API and inline SVG rendering, with no drawn shapes or data displayed yet.

Let's make a face with D3.js!

A smiley face drawn with SVG shapes animates its eyebrows in a looping motion. The example demonstrates basic DOM manipulation and transitions in D3.js v5, using `d3.select` to append circles, rectangles, and an arc-generated path for the mouth. Eyebrow movement is driven by chained `transition().duration()` calls that shift the group's `transform` attribute up and down. The face is centered via an SVG group with translated coordinates, and all styling is handled through inline attributes and a linked stylesheet.

Shapes and Colors with SVG and CSS

This example demonstrates the use of SVG shapes and colors styled through CSS, creating a minimalist visual composition. The page loads an empty `<body>` element with a linked stylesheet, while the code relies on standard SVG and CSS APIs rather than dedicated visualization libraries. The `styles.css` file resets the margin and hides overflow, providing a clean canvas for potential SVG content. The rendering approach is purely declarative, with no JavaScript or data binding visible, focusing on the foundational relationship between markup, styling, and spatial layout.
