Customizing Axes

This bar chart shows the population of the top 10 most populous countries, ordered vertically by country name, with a horizontal axis for population values. The chart highlights customized axes: the y-axis removes its domain line and tick lines, while the x-axis uses a custom tick format via `d3.format` that replaces 'G' with 'B' (e.g., 1.4B) and draws grid lines with `tickSize`. The SVG is built using `d3.scaleLinear` and `d3.scaleBand`, with axes rendered by `d3.axisBottom` and `d3.axisLeft`. Data comes from the 2018 UN World Population Prospects estimate.

Hello VizHub

This example draws a simple smiley face in a yellow circle on an SVG canvas. Using d3 v5, it imports `select` and `arc` from the D3 library to build the elements. The code positions a centered group, then adds circles for the face and eyes, with an arc path for the mouth based on specified radii and angles. All shapes are rendered as SVG primitives with hardcoded coordinates, requiring no external data source.

SVG Shapes

This example demonstrates fundamental SVG shape elements—circle, rect, and line—positioned within a fixed 960 by 960 coordinate system. The visualization compares shapes with default styling against those customized with explicit `fill` and `stroke` attributes, while a `<g>` group applies shared `fill="teal"` and `stroke="black"` to its children. Beyond these static SVG primitives, the code also showcases basic D3 integration by importing `select` from `d3` and using it to set the text content of a div element, along with a separate ES6 module export. The rendering relies entirely on SVG markup.

Cars Report

This example renders a text-based report of car listings filtered by price. The code uses D3 v5’s `select` API and vanilla DOM methods to display the generated message in a styled `<pre>` element. It imports car data from a JSON string, filters cars above a minimum price threshold, and formats each entry with a custom `formatCar` function, producing a clean, readable summary on a dark background.
