This interactive bar chart shows monthly values for a selected year, with a slider controlling the year from 2009 to 2014 and a smooth 2-second transition animating the bars to their new heights and colors. The visualization uses D3 v4 with a band scale for months, a linear scale for values, and a quantile color scale to encode magnitude. Data is loaded from six CSV files using d3.queue, and the chart updates by merging entering and existing SVG rect elements via `selection.merge` and applying axis transitions.

Six years of monthly data (2009–2014) appear as animated bar charts, with bars growing from the bottom and recolored by a quantile scale as the user drags a year slider. The visualization loads six CSV files asynchronously via `d3.queue`, then uses `d3.transition` for a two-second animated update of bar heights and axis. A range input triggers `draw()` on change, while `d3.scaleBand`, `d3.scaleLinear`, and `d3.scaleQuantile` handle positioning, scaling, and color mapping. The SVG rendering relies on `d3.axisLeft`, `d3.axisBottom`, and `.attr` transitions.

This interactive stacked bar chart displays state-level data across two years. A dropdown menu selects the year, and the visualization animates the transition between the 2017 and 2018 views. The chart uses a categorical color scale to distinguish three data ranges. The code leverages D3 v5 APIs including `d3.csv`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.stack`. Built with SVG elements, the bars and their total value labels are rendered directly, with a 750ms transition on year change.

Simple d3.js bar chart

This simple d3.js bar chart displays monthly values over a two-year period, with each bar representing a data point from a CSV file. The visualization uses d3.scale.ordinal and d3.scale.linear to map categorical dates and quantitative values, respectively, to pixel positions. Axes are rendered with d3.svg.axis, while the bars themselves are drawn as SVG rectangles with a steelblue fill. The chart includes a navigation interface with circular arrow buttons and a detail area, though the interaction logic is incomplete. Data comes from the external file bar-data.csv, and the visualization is built using the D3 version 3.5.17 library.

Simple d3.js bar chart

This bar chart displays monthly values from January 2013 through February 2014, with each bar’s height representing a numeric amount. It uses d3.csv to load data from the bar-data.csv file, d3.time.format to parse dates, and d3.scale.ordinal with rangeRoundBands to position bars along the x-axis. The chart renders as SVG, using d3.svg.axis for the rotated x-axis labels and a linear y-axis, with steelblue rectangles drawn via d3.selectAll and .enter().append. The y-axis is labeled “Value ($).”

A bar chart displays monthly values from a CSV file, with dates from 2013-01 to 2014-02 on the x-axis and dollar amounts on the y-axis. D3's d3.csv loads the data, d3.time.format parses the dates, and d3.scale.ordinal with rangeRoundBands positions each bar. The x-axis labels are rotated with SVG transforms, while steelblue rectangles encode the values. React and D3 are used in separate index.js and index.html files, though the visible rendering is entirely SVG-based.

This example shows a bar chart of country counts that updates when new data is added. It uses d3.json to load initial data from data.json, then d3.scaleLinear and d3.scaleBand to map values to positions. The visualization renders bars as SVG rectangles with d3.axisLeft and d3.axisBottom for axes. After two seconds, a new item is pushed to the dataset and re-rendered, using transition().duration(500) to animate the height of the entering bar from zero while existing bars shift via the same transition.

A bar chart displays monthly monetary values from 2013-01 through 2014-02, with each bar’s height encoding the value and labeled on the y-axis as "Value ($)." The chart uses an ordinal x-scale with rotated date labels and a linear y-scale, rendered as SVG rectangles. Built with D3 version 3.5, it employs `d3.svg.axis`, `d3.time.format`, and `d3.csv` to load and parse the `bar-data.csv` file. Data points are formatted as monthly timestamps, and axes include tick marks with rotated text for readability.

Animated bar chart

This example displays population changes over time using an animated bar chart in SVG. Bars grow in height sequentially as each year is added, with green bars that turn red and expand slightly on mouseover. The visualization is built with D3 v4, using `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` for ticks. Bar entrance animations use `transition().delay()` and `ease(d3.easeLinear)`, while hover effects rely on `transition().attr()` calls. Data comes from a CSV file with year and population values.
