This example uses a nested bar chart to show the average unemployment rate in 2017 across U.S. subregions, sorted from highest to lowest. The chart aggregates state-level data from a CSV file using d3.nest() and rollup to compute mean rates per subregion. Bars are rendered in SVG with value labels positioned inside each bar, while the code also demonstrates data grouping by region, subregion, and state, plus calculations of average unemployment rates by region.

Metis Simple Stacked Bar Chart with Labels

This example displays 2017 U.S. unemployment rates as a simple horizontal bar chart, with states sorted descending by rate and each bar labeled with its numeric value using SVG text. D3 v4 selects elements, binds CSV data, and uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. The code also demonstrates grouping with `d3.nest()` and computes average rates per region and subregion using `rollup()`. The chart is rendered as an SVG element within a 960x500 canvas.

Metis United States Unemployment Rate

This example visualizes the 2017 United States unemployment rate by state using a choropleth map. State boundaries are colored on a linear scale from light gray to purple based on the rate in the `us-unemployment.csv` dataset. The visualization includes a text summary of average unemployment by region, calculated using `d3.nest()` and `rollup`. It uses `d3.geoAlbersUsa` projection with `d3.geoPath` for rendering GeoJSON, and SVG elements with mouseover tooltips display the specific rate for each state.

Bar chart

This bar chart displays the top 10 states with the highest unemployment rates as of December 2020, ranging from Hawaii at 9.3% to New Jersey at 7.6%. The data comes from the U.S. Bureau of Labor Statistics. Using d3.csv, d3.scaleLinear, and d3.scaleBand, the visualization renders horizontal bars in SVG, with axes generated by d3.axisLeft and d3.axisBottom. The chart applies a percentage format to the x-axis ticks and includes hover effects that change bar color and opacity.

Untitled

This interactive stacked bar chart displays unemployment data across U.S. states for different years, with a dropdown menu to select the year and a checkbox to toggle sorting by total value. The visualization uses D3 v5 to render SVG elements with smooth transitions between states, animating bar positions and heights over 750 milliseconds. Data is loaded from a CSV file, and the chart employs d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, and d3.scaleOrdinal to assign category colors. Stacked segments are created using d3.stack, with labels showing each state's total.

Exercise Module 3

A horizontal bar chart displays the 2014 unemployment rate for each Spanish region, sorted from highest to lowest with grey bars sized proportionally to the rate. The visualization highlights that southern regions have higher unemployment while northern ones are lower, with hover tooltips revealing exact percentages. The code uses d3.csv to load region data and d3.selectAll with data joins to append SVG rect elements, scaling bar widths by multiplying the rate by eight.

Metropolitan Unemployment

This visualization shows the distribution of unemployment rates across 380 U.S. metropolitan areas from January 2000 to December 2012. Using a time-series heatmap, it displays monthly unemployment rate bins as colored rectangles, with darker purple indicating higher numbers of areas within a given rate range. The code uses D3 v3’s `d3.time.scale`, `d3.svg.axis`, and `d3.interpolateLab` for color interpolation. Data from the Bureau of Labor Statistics is loaded via `d3.json` and rendered as SVG rectangles.

Exercise Module 3

This example shows the unemployment rate in 2014 for Spanish regions, ordered from highest to lowest, with bar lengths proportional to the rate and tooltips revealing the exact value per region. The chart uses d3.csv to load the data, d3.descending for sorting, and d3.select to append SVG rectangles with title elements for interactivity. The data is sourced from a CSV file containing regional unemployment statistics, and the visualization is rendered as a simple SVG bar chart.

Fork of Stylized Bar Chart

This example displays the average unemployment rate for the top 10 most populous countries, rendered as a horizontal stylized bar chart with an SVG output using React. The chart uses d3.scaleBand and d3.scaleLinear to map countries and values, while d3.format formats tick labels. Data comes from the United Nations World Population Prospects 2019. Blue bars include a native SVG `<title>` element for tooltips, and loading states show "Loading..." via React hooks and the `useData` custom hook.
