This interactive stacked bar chart displays the age distribution of U.S. state populations, with a clickable legend to isolate a single age category and a checkbox to sort bars by value. Built with d3.v3 and SVG, it uses `d3.scale.ordinal`, `d3.scale.linear`, and `d3.svg.axis` to render axes and bars, while animation and a tooltip enhance interactivity. The code reads `state_data.csv` and corrects a pixel-level height calculation error from Mike Bostock’s original example.

AI-generated description

Stacked bar chart with a clickable legend to display one class of bars at a time, with the option of sorting them afterwards.

Builds on my clickable stacked bar chart, which was based on Mike Bostock's stacked bar chart and yuuniverse4444’s block #8325617, and integrates Mike Bostock's sortable bar chart.

Note: my version fixes a small inaccuracy in Mike Bostock's original code in which the heights and y-position of the bars are not calculated directly from the data value, but on the difference between the cumulative values in the stacked bar. This inaccuracy, which is usually only around 1 pixel, is not noticeable until a single category is sorted and you can see all the bars side by side in decreasing order.

My fix is a crude hack but it works!

d3js clickable stacked bar chart

This stacked bar chart displays the age distribution of each U.S. state’s population, with segments colored by age group. A clickable legend toggles individual categories on and off, and hovering over a bar segment highlights it and shows a tooltip with the exact value. Built with D3.js v3, it uses ordinal and linear scales with SVG axes, and animates bar transitions via legend-driven class selections. Data comes from the included `state_data.csv` file.

Normalized Stacked Bar Chart

This normalized stacked bar chart displays the percentage distribution of age groups across U.S. states, sorting states by the proportion of their youngest residents. Using D3 v4, it applies `d3.stack` with `stackOffsetExpand` to scale each bar to full height, then renders SVG rectangles with an ordinal color scale for age categories. Axis labels are formatted as percentages, and a custom legend anchored to each bar’s final segment identifies each series. The chart loads population data from `data.csv` and sorts states in descending order of the "Under 5 Years" share.

Radial Stacked Bar II

A radial stacked bar chart compares the age distributions of U.S. states by population. Each state is represented by a wedge whose radial extent encodes total population, subdivided by seven age bands via `d3.stack` and `d3.arc`, with a custom `d3.scaleRadial` for radial scaling. The visualization labels each state with rotated text and includes circular gridlines and a legend. Data is loaded from a CSV using `d3.csv`, and the chart is rendered as SVG in a single `<svg>` element.

Stacked Barchart with Transitions

This stacked bar chart displays the age distribution of US state populations, with each bar segmented by seven age groups and states sorted by total population. A red button triggers an update that randomly jitters the segment boundaries while preserving the overall totals, animating the transitions. Built with D3 v4, the visualization uses stacked rectangles, ordinal color mapping, and SVG transitions to morph the bars. The data is loaded from a CSV file, and the legend identifies each age category.

Stacked Bar Chart

This stacked bar chart displays the population of different states broken down by age groups, with each bar segmented into colored bands representing the age categories. The chart uses an ordinal x-scale for states, a linear y-scale for population counts, and a color ordinal scale for the age series. The visualization is rendered as SVG via D3 v3, loading data from a CSV file and using d3.csv, d3.scale.ordinal, d3.scale.linear, d3.format, d3.max, d3.keys, and d3.svg.axis. A legend identifies the age groups, while the bars are sorted by total population.

Untitled

This interactive stacked bar chart displays the distribution of three categories across U.S. states for a selected year, with a dropdown menu to switch between years. The visualization uses D3.js v5’s `d3.csv` to load data, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.stack()` to compute stacked segments. Animated transitions (via `transition().duration()`) smoothly update bar heights and axis labels. Total values for each state are shown above the bars. The SVG rendering includes axis groups and colored layers, with the year selector populated from the dataset.

Radial Stacked Bar III

A radial stacked bar chart displays the population distribution of U.S. states across seven age groups from the provided CSV data. The visualization arranges states as sectors around a center, with each sector subdivided into colored segments representing age categories. Labels rotate around the circumference, and circular grid lines with tick labels indicate population values. The code uses a custom `d3.scaleRadial` extension built on `d3-scale`, combined with `d3.scaleBand`, `d3.stack`, and `d3.arc` to render SVG paths. A weaving algorithm reorders states to improve label legibility.

transition of bar chart

This interactive bar chart compares the proportions of different age brackets across U.S. states, using a dropdown menu to switch between age groups. Built with D3 v4 and rendered as SVG, the visualization animates horizontal bars as the selected age bracket changes, with bars transitioning vertically, resizing horizontally, and labels and value texts updating smoothly. The chart is based on data from a CSV file, normalizing each state's population by age bracket to percentages, and displays the top 10 states for the selected age group. Interactivity includes a dropdown menu and a keyboard modifier (Alt) to control animation speed, with a default auto-advance after 5 seconds.
