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.

Bar Chart

This example presents an animated bar chart of country values, with data loaded from a CSV file. The chart visualizes numerical values for each country using horizontal bars, with axes positioned on the left and bottom. It imports D3 functions like `csv`, `scaleLinear`, `scaleBand`, `axisBottom`, and `axisLeft` to construct the visualization. The bars transition in width over 800 milliseconds, with each bar sequentially delayed using `transition.duration` and `delay`. The SVG rendering includes a styled message from a local ES6 module, all within a pink-background container.

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.

new d3

This example displays a horizontal bar chart of the populations of five countries, with bars animating to a reduced opacity on mouseover and a tooltip indicating the country name. The visualization loads population data from a local CSV file, and uses D3 v6’s modular `select`, `csv`, `scaleBand`, `scaleLinear`, `axisBottom`, and `axisLeft` APIs to construct the SVG bar chart. The code applies custom tick formatting for millions and uses a transition to animate bar opacity, while omitting axis lines and ticks for the categorical axis.

D3 Bar Chart

This interactive D3 v4 bar chart displays two datasets of numbers as vertical steel-blue bars with value labels and a y-axis. Clicking the Update button toggles between a 10-element ascending dataset and an 8-element descending one, demonstrating the enter, update, and exit pattern. The code uses d3.scaleLinear for the y-scale, d3.axisLeft for the axis, and transition().duration(500) to smoothly animate bar heights, positions, widths, and labels when the data changes. SVG rendering handles all visual elements.

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.

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.

Data Updating

This example demonstrates dynamic data updating in a bar chart built with D3.js v6 and rendered as SVG. The interactive visualization allows users to add or update data entries via input fields, triggering smooth transitions on bar widths as weights change, while axis scales adjust accordingly. Users can also filter the displayed data by setting a minimum weight threshold. The code employs `d3.csv` for data loading, `d3.scaleLinear` and `d3.scaleBand` for scales, and the data join pattern with `enter`, `merge`, and `exit` selections, alongside `transition` and `d3.axisLeft`.

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.
