This example shows a simple smiley face drawn using D3.js v5 in an SVG container. The face consists of a large yellow circle for the head and two smaller black circles for the eyes, positioned with fixed pixel offsets. The code selects the SVG element and appends circles using D3’s `select` and `append` methods, setting attributes like `cx`, `cy`, `r`, and `fill` directly. The face’s dimensions derive from the SVG’s width and height attributes, with the head radius calculated relative to the height. No data source is used; the visualization is purely procedural.

Let's make a face with D3.js!

This example demonstrates how to build a smiley face using fundamental D3.js DOM manipulation, with a yellow circle for the head, black circles for the eyes, and an arc path for the mouth. The code uses D3’s `select` and `arc` APIs to append SVG elements to an `svg` container, positioning them based on the SVG’s width and height attributes. It renders entirely as SVG in the browser, importing D3 v5 from a CDN. The example highlights basic shape creation and attribute setting without data binding or interaction.

Let's make a face with D3.js!

This example demonstrates how to build a simple smiley face using D3.js, with a yellow circle for the head, black circles for the eyes, and an arc for the mouth. The code uses D3’s `select` and `arc` APIs to create and position SVG elements, relying on the `attr` method to set coordinates and dimensions based on the SVG’s width and height. The face is rendered entirely in SVG, with no external data source, and serves as a basic introduction to DOM manipulation with D3.

Let's make a face with D3.js!

This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG shapes: a yellow circle for the head, two black circles for eyes, and a mouth drawn as a path. The code uses d3.select, d3.arc, and SVG attribute setters like .attr() to position elements on a 960x500 canvas. Static in this version, it serves as an introduction to D3’s data-driven approach, laying groundwork for an animated version where eyebrows move (per the README). The project runs on D3 v5 with SVG rendering.

Let's make a face with D3.js!

This example shows a yellow smiley face built with SVG shapes, including a face circle, two eyes, and animated eyebrows that move continuously. It demonstrates fundamental D3.js DOM manipulation using method chaining with `d3.select` and `svg.append`, setting attributes like `r`, `cx`, `cy`, `fill`, and `stroke` on circle elements. The code uses D3 v5 from the `d3` module, importing `select` and `arc` (though `arc` is not used in the visible code). The face is rendered in a fixed 960x500 SVG canvas, with eye positions calculated from the width and height.

Let's make a face with D3.js!

This example demonstrates how to build a smiley face with D3.js, using SVG elements for rendering. It shows a yellow circle with eyes, eyebrows, and a mouth, where the eyebrows are positioned as rectangles. The code uses `d3.select`, `d3.append`, and `d3.arc` to construct the shapes, with attributes set manually for placement. The face is centered via a translation on a group element, and the mouth is drawn as an arc path. The example highlights fundamental DOM manipulation and SVG shape creation in D3.

Let's make a face with D3.js!

A yellow smiley face is drawn on an SVG canvas using D3.js v5, with two black eyes and an arc-based mouth positioned relative to the center of the 960x500 viewport. The code explicitly sets circle radii, coordinates, and fill/stroke attributes, while the mouth uses the d3.arc() helper to generate a path with defined inner and outer radii and angle ranges. Static geometric values define the face’s proportions, with no dynamic data or interaction involved.

Let's make a face with D3.js!

This example uses D3.js v5 to construct a smiley face entirely through SVG elements in the DOM. It draws a yellow circle for the face, black circles for the eyes, and a path generated with the `d3.arc` function to form the mouth. The code demonstrates fundamental selections, attribute setting, and shape generation using APIs like `select` and `arc`. The resulting static face is rendered in an SVG container.

Let's make a face with D3.js!

This example uses D3.js to draw a simple, smiling face entirely from SVG primitives. A yellow circle forms the head, two smaller black circles serve as eyes, and two rectangles act as eyebrows. The mouth is created using D3's `arc` generator, which defines a path with a specified inner and outer radius and angular range. The code positions all elements relative to a central `g` group, using D3’s `select` and `append` methods to build the SVG structure.
