This visualization shows the U.S. population distribution across age groups from 2010 to 2019, using a slider to animate between years. It renders an SVG bar chart with D3 v4, where each bar’s height and color encode population size via `d3.scaleLinear` and `d3.scaleQuantile`. Transitions smoothly update bars and axes over two seconds. Data is loaded from ten CSV files using `d3.queue` and `d3.csv`. The code relies on D3’s `scaleBand`, `axisBottom`, `axisLeft`, and `transition` APIs.

Population and age

An interactive bar chart displays population distribution across age groups for selected years, with a slider controlling the year from 2015 to 2019. The visualization uses D3 v4’s `scaleBand`, `scaleLinear`, and `scaleQuantile` for positioning and color encoding, with SVG rectangles animated via `transition`. Data is loaded from CSV files using `d3.queue` and `d3.csv`, while React state is not actually implemented despite the framework metadata.

Untitled

This chart displays the population distribution across six U.S. states, broken down by seven age brackets. Each state’s data is shown as a group of colored bars, with a legend that allows users to click on age categories to filter which bars remain visible. The visualization uses D3 v5 with a band scale for grouping, a linear scale for the y-axis, and an ordinal scale for colors. It is rendered as an SVG, and clicking a legend item triggers a transition that updates the visible bars and rescales the axes.

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.

Population

A horizontal bar chart displays the 2020 population of ten countries, sourced from a CSV file and rendered as SVG elements. The visualization uses React with a `useEffect` hook to fetch and parse the data via `csv`, then applies D3's `scaleBand` and `scaleLinear` for positioning. Gridlines and axis labels are generated from `xScale.ticks()`, while each country's bar length reflects its population value.

Population

This bar chart displays the population of 20 U.S. states ranked along the vertical axis. Each horizontal bar’s length corresponds to the state’s population value. Built with React and D3 v5, it uses `d3.csv` to load data, `scaleBand` for the categorical y-axis, and `scaleLinear` for the numeric x-axis. SVG rectangles represent bars, with manual tick rendering via `.ticks()` and gridlines. The chart includes labeled axes and a blue gridline accent.

Making a Bar Chart

This bar chart shows the population distribution across age groups (from 0-4 to 95+ years) for a given population. Using D3.js version 5, it employs `d3.scaleLinear` and `d3.scaleBand` to map population values and age categories to the x and y axes, respectively. The SVG includes axes via `d3.axisLeft` and `d3.axisBottom`, with bars rendered as `rect` elements filled in steel blue. The data is loaded from a CSV file containing country and population columns.

Untitled

This visualization displays a stacked bar chart of U.S. state populations segmented by age groups, sorted by total population. The React-based example uses D3.js v3 to generate SVG bars with an ordinal x-axis, linear y-axis, and a color scale. Interactive features include hover tooltips showing segment values and a legend that filters bars on click. Data is loaded from an external CSV file, and animations are triggered through legend selections.

Population over the years

A horizontal bar chart displays the populations of the top 15 countries for a selected year, using data from the United Nations World Population Prospects 2019. A dropdown menu lets the viewer change the year, updating the bar lengths accordingly. The visualization uses React with D3 v5 scales (`scaleBand` and `scaleLinear`) to position bars and axes, and renders SVG elements for the chart. Population values are formatted using D3's `format` with SI prefixes, and each bar includes a tooltip showing the exact value.
