Scatter Plot with Menus

This scatter plot animates the Iris dataset, cycling through different feature pairs every two seconds. The visualization uses D3.js v6 and React, rendering SVG circles and axes. A reusable chart component (`scatterPlot`) manages the scales, marks, and axes, with the main script updating the x-axis values via `setInterval`. Data is loaded from a remote CSV, parsed, and mapped to pixel coordinates.

Reusable D3 Scatter Plot

This reusable scatter plot displays the Iris dataset, mapping petal and sepal measurements as animated circles. Built with D3 v6 and React, it uses `scaleLinear` to project data values to pixel coordinates, with `d3.axisLeft` and `d3.axisBottom` for axes. The `scatterPlot` function returns a configurable chart instance, toggling between four measurement columns on the x-axis via `setInterval` every two seconds. SVG circles are joined with data, and transitions update their positions smoothly.

Reusable D3 Scatter Plot with Symbols

This example shows a reusable D3 scatter plot displaying the Iris dataset, with each species represented by a distinct symbol (circle, diamond, and triangle). The chart maps petal length on the x-axis and sepal length on the y-axis, using axes generated with `d3.axisLeft` and `d3.axisBottom`. The implementation uses `d3.scaleLinear` for positioning, `d3.scaleOrdinal` and `d3.symbol` to assign symbols to species, and a modular JavaScript structure with getter-setter functions to configure width, height, margins, and accessor functions. Data is loaded via `d3.csv` from a GitHub gist URL.

D3 Scatter Plot

This example visualizes the classic Iris dataset as a D3.js scatter plot, mapping sepal length on the y-axis and petal length on the x-axis. The chart renders as an SVG with circles positioned via linear scales, while axes are drawn using `d3.axisLeft` and `d3.axisBottom`. The code fetches CSV data asynchronously, parses numeric columns, and dynamically resizes the plot to the full window. It customizes tick label styling through CSS and uses a React starter environment.

D3 Selection Exploration

A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.

JavaScript Arrays - Vanilla HTML

This example demonstrates how to sort an array of objects in JavaScript using the D3 ascending comparison function. The code defines a custom range generator function, creates an array of ten numeric values, and builds an array of key-value entries. It logs the entries sorted alphabetically by key through the Array.sort method, with D3 6.6.2 imported as a dependency. The visualization is plain vanilla HTML with no visual output, focusing purely on algorithmic array manipulation.

Sol LeWitt Reproduction with D3

This example reproduces a Sol LeWitt-inspired drawing using the D3.js library in a React framework, rendered as scalable vector graphics. The code creates an SVG canvas that fills the browser window and applies circular masks to horizontal and vertical striped rectangles, producing an overlapping grid pattern. The implementation uses D3’s `select` method to build the SVG element and appends shapes programmatically, though the mask and rectangle logic is commented out, leaving only the blank SVG. The visualization adopts LeWitt’s geometric, rule-based aesthetic.

Sol LeWitt Reproduction

This example reproduces a Sol LeWITT drawing using raw SVG and JavaScript, without any external libraries. It renders 100 horizontal and 100 vertical striped rectangles that intersect to create a geometric grid, with two circular masks applied to reveal different portions of the stripes. The `mask` element and `circle` primitives define a central circular boundary, while the second mask inverts its effect. The visualization spans the full browser window by reading `window.innerWidth` and `window.innerHeight`. The code constructs SVG elements programmatically via `document.createElementNS` and sets attributes directly, demonstrating a minimal approach to generative art.

Sol LeWitt Reproduction

This example reproduces a minimalist Sol LeWitt drawing using programmatically generated vertical bars. It fills the browser viewport with 100 thin SVG rectangles, evenly spaced 20 pixels apart and spanning the full window height. The code uses the raw Document Object Model (DOM) API with `createElementNS` to construct SVG elements directly, setting viewport dimensions from `window.innerWidth` and `window.innerHeight`. No external libraries are used; the rendering relies purely on vanilla JavaScript and CSS.

Pseudo Bar Chart

This pseudo bar chart uses black rectangles to represent categorical values A through D, with varying heights that suggest a bar chart’s visual hierarchy while omitting traditional axes. The SVG code explicitly places four rectangles and paired text labels, demonstrating a static, hand-coded layout. It relies on React’s rendering approach via the v3 framework, though the visible implementation uses raw SVG elements and CSS styling with the Share Tech font. No data binding or dynamic computation occurs; the chart is purely declarative.

Pseudo Scatter Plot

This pseudo scatter plot presents six black ellipses arranged across a white 960x500 SVG canvas, simulating the appearance of a scatter plot without underlying data points. Each ellipse is manually positioned at varying coordinates with consistent rx and ry values of 40.5 and 39, creating uniform circular shapes. The visualization uses raw SVG elements—specifically `<rect>` for the background and `<ellipse>` for the marks—embedded directly in HTML with minimal CSS to remove margins and scrolling. No JavaScript libraries or data processing are involved; the rendering relies entirely on static SVG markup.

SVG Fundamentals

This example demonstrates fundamental SVG shape elements—circles, rectangles, lines, and paths—statically positioned on a 960×500 canvas. It shows how fill, stroke, stroke-width, and coordinate attributes control appearance, while explaining that no z-index exists; the document order determines stacking. The code uses raw SVG markup within an HTML page, with CSS resets for margins and overflow. Path commands like `M` and `L` illustrate absolute positioning, contrasting with relative `l` syntax, providing a hands-on introduction to SVG’s drawing model for future data-visualization work.
