This example demonstrates a minimal bar chart template using D3, rendering four country population values as equal-sized squares. The SVG canvas is initialized with fixed dimensions, and the code loads data from a CSV file via `d3.csv`. Each rectangle is appended using the data join pattern (`.selectAll('rect').data(data).enter().append('rect')`), though all bars share the same 300×300 size. The visualization relies on D3 v6’s module imports, `select` and `csv`, to process the data and update the DOM without any scales or axes.

D3 init

A minimal bar chart maps country populations from a CSV file to SVG rectangles. The code loads `data.csv` using `d3.csv`, multiplies each population value by 1000, and renders horizontal bars with `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. It appends rectangles to an SVG element selected via `d3.select`, with dimensions derived from the scales and a fixed margin offset. The example demonstrates a basic D3 v5 data-joining workflow with asynchronous data loading.

HTML Starter

This example shows a bar chart of population data for several countries, rendered as SVG rectangles. The visualization loads data from a CSV file using `d3.csv`, converts population values to numbers, and maps them to bar widths with `d3.scaleLinear`. Country names are mapped to vertical positions using `d3.scaleBand`, though the range is left empty. The code appends a static SVG canvas and rects without explicit x or y positioning, leaving the chart incomplete. It demonstrates a minimal HTML page combining D3 v6 and vanilla JavaScript.

HTML Starter

This example displays a bar chart of country populations using a horizontal layout, with countries on the y-axis and population on the x-axis. The code loads data from `data.csv` and renders SVG rectangles through D3’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs. It uses `d3.csv` to parse the data, converts population values to numbers, and then draws the chart within a pre-defined SVG element. The visualization is a minimal starter template demonstrating D3 v5 with React.

Making a Bar Chart

This example demonstrates the initial step of building a bar chart with D3, loading population data from a CSV file and rendering static rectangles for each country. The bars are drawn as SVG rectangles with fixed width and height, and the population values are parsed and multiplied by 1,000. It uses `d3.csv` to load the data, `d3.select` to target the SVG, and the `enter` selection to append the rectangles. Styling is minimal, with no axes or scales applied yet.

Fork of D3 Starter

This fork of the D3 Starter demonstrates a minimal bar chart that displays population data for several countries, sourced from a local CSV file. The visualization maps each country to a rectangle, with the height and width fixed while the data is read and logged. Built with d3.v7, the example uses `csv`, `scaleLinear`, `max`, and `select` APIs to parse data and prepare scales, though the rendered rectangles do not yet reflect the data values. The chart is drawn as SVG within a 960x500 canvas, with the data population values multiplied by 1000 during preprocessing.

HTML Starter

This example shows a simple bar chart of population by country, rendered as an SVG using D3 v6. The chart maps population values to bar widths with `d3.scaleLinear` and country names to vertical bands with `d3.scaleBand`. Data is loaded from a CSV file using `d3.csv`, parsed into numbers, and then appended as `rect` elements to an SVG. The code demonstrates a bare-bones HTML page combining inline CSS, JavaScript, and D3 to create a static visualization.

HTML Starter

This example uses D3 v5 to render a horizontal bar chart of population data from a CSV file. The SVG canvas displays each country as a bar, with bar width proportional to population using a linear scale and bar position determined by a band scale. Data is loaded via D3’s `csv` function, and the chart is drawn by appending `rect` elements to the SVG. The code uses `scaleLinear`, `scaleBand`, and `max` from D3 to map values.

Making a Bar Chart

This example demonstrates a basic bar chart of country populations using D3.js v5 with SVG rendering. The visualization maps each country from a CSV data file to a rectangular bar, though the bars are uniformly sized rather than scaled to population values. The code imports `select`, `csv`, and `scaleLinear` from D3, loads the data asynchronously, converts population strings to numbers, and appends rectangles to an SVG container. The `scaleLinear` function is instantiated but not fully configured, and the bars are fixed at 300 by 300 pixels each.
