Making a bar chart

A D3.js bar chart displays population figures for the world’s most populous countries, loading values from a CSV file and preparing them for rendering inside an SVG canvas. The code uses the `select` API to target the SVG element and the `csv` function to asynchronously fetch and parse the data, converting the population strings to numbers. The SVG viewport is set to 960 by 500 pixels, though the example currently logs the parsed data to the console without yet drawing bars or axes.

Let's make a face with D3.js!

A smiling face built from SVG shapes animates through D3.js v5, using circles for the eyes and face, rectangles for eyebrows, and a path with the d3.arc generator for the mouth. The code demonstrates SVG element construction, attribute binding, and a chained transition that moves the eyebrows up and down over two seconds. A decorative bindhi path and sparkle circle add detail, with all elements grouped and translated relative to the SVG canvas center.

Hello VizHub

This example demonstrates a minimal D3.js visualization that renders a static message, “Hello VizHub!”, centered on the page. It shows how D3 can be used for basic DOM manipulation, using the `select` API to target an HTML element and set its text content. The project also illustrates the use of ES6 modules, with the message string imported from a separate file, and a local CSS file for styling. The code loads D3 version 5.9.1 from a CDN.

Cars Report

This example displays a text-based report of cars filtered by price, showing the make, model, year, and cost for vehicles under $2,000. The page initially shows a loading message while a simulated asynchronous data fetch runs via a Promise with a two-second delay. The code uses ES6 modules, `JSON.parse` to load hardcoded car data, and the `Promise` API to handle the delayed response. Once loaded, the `generateReport` function filters, formats, and joins the car entries into a single string displayed in an HTML `<pre>` element.
