Shapes with SVG and CSS

A single large SVG circle fills the viewport, rendered with a hardcoded `r="400"` attribute and no visible styling. The example demonstrates basic SVG shape creation within an HTML document, using the SVG `circle` element directly in markup and a linked external stylesheet that resets margins and hides overflow. No JavaScript libraries or data sources are involved; the visualization is purely static, showcasing the minimal setup required to display a geometric primitive with SVG and CSS.

Fork of Customizing Axes

A bar chart displays student scores from a CSV file, ranking each student on a vertical band scale against a linear grade axis. The visualization customizes axes by removing default domain lines, adding grid lines, and applying a formatting function that converts large numbers to abbreviated labels using D3's `format`. It uses `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render SVG bars with styled ticks and titles.

Fork of Making a Bar Chart

This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects. It uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render the SVG visualization, with custom tick formatting converting values to billions. The chart removes axis domain lines and includes a title and x-axis label, styling bars in steelblue via CSS.

Fork of Making a Bar Chart 3

This bar chart visualizes student test marks, with each bar’s length representing a score from 1 to 100. Built with D3 v5, it uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for categorical student labels, and `d3.axisBottom` with a custom tick formatter that abbreviates numbers. The SVG renders steel-blue rectangles, and the chart includes axis labels and a title. Data is loaded from a CSV and multiplied by 1,000 during preprocessing.

Fork of Making a Bar Chart

This chart shows the marks of 10 students as individual bars. The bar lengths encode the mark values, while the vertical positions correspond to each student’s ID. The visualization uses d3’s `scaleBand` and `scaleLinear` to map student IDs and marks to SVG pixel coordinates. The data is loaded from a CSV file using d3’s `csv` function, and the marks are parsed to numbers before rendering. Each bar is drawn as a `rect` element, with the bar’s height derived from `yscale.bandwidth`.
