Line Chart

This line chart displays temperature readings over the course of a week, with time on the x-axis and temperature on the y-axis. The visualization uses React components to render SVG axes and marks, employing D3 scales such as `scaleTime` and `scaleLinear` to map data, and the `line()` generator with `curveNatural` to create the smooth path. Data is loaded from a CSV file using `d3.csv`, and each data point includes a circle with a tooltip showing the day.

Scatterplot

This scatterplot visualizes the Iris dataset, plotting sepal length against sepal width for individual flower samples, with the data loaded via `d3.csv` and rendered as SVG circles using React. The code uses `d3.scaleLinear` with `d3.extent` and `.nice()` to compute continuous scales for both axes, while custom React components generate the axis ticks and marks. Each point includes a tooltip via an SVG `<title>` element, and the chart includes rotated and positioned axis labels.

Rendering Data with React & D3

An interactive bar chart displays the top 10 most populous countries in 2020, sourced from UN population data. It uses React to render SVG elements declaratively, with D3's scaleBand and scaleLinear for axis mappings. Custom React components (AxisBottom, AxisLeft, Marks) handle ticks and rectangles, while D3's csv loader fetches and parses the data.

Smiley Face p1

A reusable React component renders a yellow smiley face inside an SVG, centered on a 960 by 500 canvas. The face’s circular background, two black eyes, and an arc-shaped mouth are built from individual React components. D3’s `arc` generator creates the mouth path, while `FaceContainer` applies a translation to center the drawing. The code uses React 17 and D3 v7, with SVG circles and paths for all visual elements.
