Bar chart made with d3.js

Bar chart

This bar chart displays the average weight of different species, categorized by continent, revealing which regions harbor the largest animals. The visualization fetches its data from a remote JSON file via `d3.json`, then uses `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis. SVG rectangles are drawn for each species, with axes created using `d3.axisBottom` and `d3.axisLeft`. The chart applies a custom tick format via `d3.format` to abbreviate large numbers, and all rendering occurs in SVG.

Bar Chart Using CDC Data Describing Height for Males vs. Females

This bar chart visualizes CDC data on height by gender, showing the distribution of heights for males versus females using horizontal bars. The chart is rendered with D3 v7’s `scaleLinear` and `scaleBand` for axes, with `axisLeft` and `axisBottom` for tick marks, and SVG rectangles for the bars. Data is loaded from a CSV file using `d3.csv` and processed to numeric values. The visualization uses a simple steelblue fill and a fixed margin layout.

bar

A horizontal bar chart displays population figures for ten countries, sorted by value, with each bar’s length proportional to its population. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render SVG rectangles and axes. Data is loaded from a CSV file and parsed with `csv`. After initial rendering, the chart animates by applying a `transition` with a staggered `delay` to reposition the bars, though the animation targets undefined scales and does not visibly alter the chart.

Making a bar chart with D3.js!

This example shows a horizontal bar chart of country populations, using bar length to encode population size and the y-axis to list country names. The visualization renders in SVG and loads data from a CSV file, converting population values to numbers before scaling. The code builds the chart with D3 v5 functions including `csv`, `scaleLinear`, `scaleBand`, `axisBottom`, `axisLeft`, and `select`, positioning bars within a margin-based layout. Rectangles are appended via a data join, with widths mapped from the linear scale and heights from the band scale.

Bar chart

This bar chart shows the population of various countries in 2020, with horizontal bars whose lengths are proportional to population values. The chart uses D3 v5 to load data from a CSV file, scale the values linearly for the x-axis, and use a band scale for the categorical y-axis. The SVG rendering is organized within a translated group, with axis elements produced by `axisLeft` and `axisBottom`. Rectangles are appended for each data point, using the scales to position and size them.

Bar Chart using D3.js

This visualization presents a simple bar chart of a fixed dataset representing eight numerical values, rendered as SVG rectangles using D3.js v4. The chart does not display axes or labels, relying instead on the raw bar lengths to convey magnitude against an implicit baseline. Using the `d3.select` and `selectAll` APIs, the code generates each bar’s height proportionally to its data value and applies a translate transform to position bars side by side with a fixed padding. The underlying data appears to be an arbitrary array rather than the UN population data referenced in the README, and the chart updates only on load with no interactive elements.

Making a Bar Chart

This example shows a horizontal bar chart of population counts for twelve countries, with each bar’s length scaled linearly and country labels aligned on the vertical axis. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `selectAll().data().enter().append()` to render SVG rectangles. Data is loaded from a CSV file via `d3.csv`, with population values converted from numeric strings to numbers by multiplying by 1000. The chart applies fixed margins and transforms to position axes and bars within an SVG container.

Making a Bar chart using D3.js

This example shows a horizontal bar chart of country populations using D3.js v5, with each bar’s length scaled linearly to the population value and country names on the y-axis. The SVG rendering uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical y-axis, and `d3.axisBottom` and `d3.axisLeft` to draw the axes. Data is loaded asynchronously from a CSV file, with population values converted from thousands to raw counts. Bars are appended as `rect` elements and styled with steelblue fill via CSS.
