Fork of Stylized Bar Chart

This chart displays the top 10 most populous countries as horizontal bars, ranked by population with country names on the y-axis. Bars are rendered as SVG rectangles using React components, with data loaded from the UN World Population Prospects 2019 via d3.csv. The visualization employs d3.scaleBand for categorical positioning and d3.scaleLinear for quantitative values, while d3.format abbreviates tick labels (e.g., "1.3B"). Axes and marks are generated through React’s component pattern, and a native SVG `<title>` element provides hover tooltips showing the exact population.

Smiley Face Part 1

This example displays a static smiley face rendered as three SVG circles: a large yellow head and two smaller outlined eyes, all positioned with hardcoded coordinates. The head uses a yellow fill and black stroke, while the eyes are black outlines without fills, creating a simple cartoonish expression. The visualization is built with plain SVG markup embedded directly in the HTML, not using the included React starter code, which only renders a "Hello React!" message. The code also loads React 16.13.1 via UMD scripts but the face itself does not rely on any JavaScript or React components for its drawing.

Smiley Face Part 1

This example shows a basic smiley face drawn as three circles in an SVG: a large yellow face and two smaller eyes, with black strokes for outlines. The code uses plain SVG elements—`<svg>`, `<circle>`, and CSS styling—inside an HTML page to achieve the rendering. The positioning of the eyes is hardcoded via `cx` and `cy` attributes. It demonstrates a minimal static visualization without interactivity or data binding.
