This grouped bar chart displays state populations across seven age ranges, with each state’s bars clustered along the x-axis and a color-coded legend for age groups. Built with D3.js and Crossfilter, the code loads data via `d3.csv`, uses `d3.scale.ordinal` for positioning and color, `d3.scale.linear` for the y-axis, and `d3.nest` to structure grouped data. Crossfilter dimensions and groups aggregate the CSV records, while `d3.svg.axis` renders axes and `d3.format` applies SI prefixes. The SVG output includes hover-free static bars and a legend.

AI-generated description

This is a fork of mbostock's grouped bar chart example, to demonstrate how to use crossfilter to produce the same result.

This grouped bar chart is constructed from a CSV file storing the populations of different states by age group. The chart employs conventional margins and a number of D3 features:

Grouped Bar Chart with Crossfilter

This grouped bar chart visualizes state populations by age range, with states on the x-axis and population on the y-axis using a linear scale with SI formatting. Each state is divided into age-group bars, colored distinctly, with a legend. The chart uses crossfilter to dimension, group, and aggregate the CSV data, computing nested structures via d3.nest to organize values by state and age range. Margins frame the SVG, axes are generated with d3.svg.axis, and the population encoding uses d3.scale.linear with d3.format for compact labels.

Grouped Bar Chart with Crossfilter

This grouped bar chart displays population counts by age metric (Under 5 Years, 5 to 13 Years, 14 to 17 Years) across years 2011–2016, using a CSV dataset. The visualization is built with D3 version 3.5.5 and crossfilter 1.3.12. It uses d3.csv for parsing, d3.scale.ordinal for x-position and color encoding, d3.scale.linear for y-position, d3.svg.axis for axes, and d3.nest to group data for rendering as grouped SVG bars. A legend identifies each age metric by color.

Grouped Bar Chart

This grouped bar chart displays the population distribution across seven age groups for six U.S. states, using a distinct color for each age bracket. The chart is rendered as SVG, with bars grouped per state along the x-axis and population counts on the y-axis, formatted with SI prefixes like "10M." Built with D3 v4, the visualization loads data from a CSV file via `d3.csv`, uses `d3.scaleBand` for the x-positions and `d3.scaleLinear` for the y-axis, and applies an ordinal color scale. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and a legend is manually constructed with SVG rectangles and text.

Grouped Bar Chart

This grouped bar chart displays the populations of six U.S. states across seven age groups, loaded from a CSV file via d3.csv. The visualization uses d3.scaleBand for the state and age-group positions, d3.scaleLinear for the population axis, and d3.scaleOrdinal with a categorical color range to distinguish age categories. Bars are rendered as SVG rectangles, with axes generated by d3.axisBottom and d3.axisLeft, while d3.format applies SI prefixes (e.g., “10M”) to tick labels. A legend maps colors to age groups.

d3fc grouped bar chart

This grouped bar chart displays the population distribution across seven age brackets for six U.S. states, with each state’s bars encoded by a categorical color scale. The visualization is rendered as SVG using d3fc’s `seriesSvgGrouped` and `chartCartesian` APIs, with `d3.scalePoint` for the x-axis and `d3.scaleLinear` for the y-axis. Data is loaded from a CSV via `d3.csv`, and the legend is generated using `d3.legendColor`. The y-axis uses `d3.format(".2s")` to abbreviate large population values.

Grouped Radial Bar Chart

This grouped radial bar chart visualizes the population distribution across seven age brackets for six US states. Each state occupies a circular sector, divided into seven colored segments whose radial lengths represent population counts, with dashed circular gridlines and a legend for age categories. Built with D3 v3, it renders as SVG and animates each segment’s growth using `transition.attrTween` with an elastic easing. The code loads data from a JSON file, scales values with `d3.scale.linear`, and draws paths via `d3.svg.arc` and an axis using `d3.svg.axis`. State names appear as circular text along a path.

Stacked Bar Chart

This stacked bar chart visualizes the population of each U.S. state, broken down by seven age groups, with states sorted by total population. The data is loaded from a CSV using d3.csv. The chart uses d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis with SI prefix formatting via d3.format, and d3.scaleOrdinal with a categorical color palette. d3.stack computes the stacked series, which are rendered as SVG rectangles, with axes generated by d3.axisBottom and d3.axisLeft.

Untitled

A grouped bar chart displays population estimates for six U.S. states across seven age brackets, colored by age group via a categorical color scale. Using D3 v4, the visualization loads CSV data with `d3.csv`, employs `d3.scaleBand` and `d3.scaleLinear` for axes, and renders SVG rectangles for bars. A legend maps age ranges to colors, while axis labels and a title clarify the data. The chart is built with a `svg` element and D3’s selection, scale, and axis APIs.
