Stylized Bar Chart

This stylized bar chart displays the top 10 most populous countries using data from the United Nations World Population Prospects 2019. It uses React with D3.js v5 functions like `scaleBand` and `scaleLinear` to map country names and population values, rendering horizontal bars as SVG rectangles. The chart includes formatted axis ticks via d3's `format` API, with axis labels and tooltips styled through a Poppins font and custom CSS. All marks, axes, and labels are built from modular components (AxisBottom, AxisLeft, Marks) that leverage React's component structure.

A scatter plot visualizes the Iris dataset, encoding sepal and petal measurements as points colored by species. The chart uses D3 v3 scales and axes to map numeric values to pixel positions, with an SVG rendering of circles and a color legend. The React-based application loads the data via the `csv` function from D3, and interactive tooltips display the iris variety and coordinates on mouseover.

Making a Bar Chart

This bar chart displays the population of ten countries, with bars ordered alphabetically by country name. The chart uses D3 v5's `scaleLinear` and `scaleBand` to map population values to bar widths and countries to vertical positions, respectively. Data is loaded from a CSV file via D3's `csv` function, and the SVG bars are appended and sized through the `selectAll` and `attr` methods. The rendering occurs in an SVG element with a fixed width and height.

Let's Make a Face

This example constructs a simple cartoon face from basic SVG shapes, rendered as a yellow circle with two black eyes and a curved mouth. Built with React and D3.js (v5), it uses `d3.select` to target the SVG element and appends circles for the face and eyes. The mouth is drawn using D3's `arc()` generator, which creates a path based on specified inner and outer radii and angular ranges. The visualization operates entirely with static, hard-coded values, with no interaction or external data.
