Making a bar chart

This example demonstrates how to build a basic bar chart from a dataset of country populations. It loads data from a CSV file using `d3.csv`, parses the population values, and maps each row to a rectangle element in an SVG canvas. The code uses D3’s `select` and `scaleLinear` (though scaling is not yet applied), and appends `rect` elements with fixed dimensions inside a 960×500 SVG. The visualization serves as a starting point for showing raw data as simple blocks before adding axes or proportional scaling.

Let's make a face with D3.js

This example shows how to build a cartoon face using D3.js v5 SVG primitives, assembling circles for the head and eyes with rectangles for eyebrows and an arc-generated path for the mouth. The code positions these elements within a centered group using translate transformations, while the d3.arc API calculates the mouth’s curved shape based on specified inner and outer radii and angle ranges. All shapes derive their attributes from explicit numeric constants, demonstrating manual coordinate layout rather than data binding or scales.

Untitled

This example shows an interactive network graph of nodes and links that respond to mouse hover and drag actions. Using d3.forceSimulation for physics-based layout, the visualization renders nodes as circles with labels and uses color-coded links to represent connections between data points. The graph incorporates zoom and pan controls for exploring the network structure, and the code leverages d3.drag and d3.zoom APIs. The underlying data appears to be a small, hardcoded set of relationships displayed in a force-directed layout.

Hello VizHub

This example demonstrates how to display a static text message using D3.js within a web page. It renders the greeting “Hello VizHub!” inside a large, centered div element with a dark blue background and white Ubuntu font. The code imports the `select` function from D3 v5 and uses it to set the text content of the div, while a separate ES6 module exports the message string. The page loads D3 from a CDN and applies styling through an external CSS file.

Hello VizHub

This example demonstrates a minimal “Hello VizHub!” message rendered as large, centered text on a dark blue background. It serves as a basic template for showing how a VizHub project is structured with separate HTML, JavaScript, module, and stylesheet files. The code imports D3’s `select` function to target a `div` by its `id` and sets its text content from an exported ES6 module variable. The styling uses an imported Ubuntu font from Google Fonts and applies a responsive font size of 12em.
