This example displays the U.S. Census Bureau’s County Business Patterns data for 2020, showing employment figures and firm-size distributions across different industry classifications within a chosen Combined Statistical Area. The visualization presents the dataset as a raw table, allowing users to inspect the hierarchical NAICS codes alongside metrics like annual payroll, number of establishments, and employee count brackets. Under the hood, the code fetches the CSV, parses it with `d3.csvParse`, and converts numeric strings to numbers before rendering the JSON structure into a `<pre>` element via D3’s `selectAll` and `join` operations.

County Business Practices

About

Data from census.gov about employment for business within countys in the US
https://www.census.gov/programs-surveys/cbp/data/datasets.html
Have data over many years
Data organized by year, but I may only pull data from my county/town/state and then combine it with data from different years
I included only 2020 data using Combined Statistical Areas (CBA) as an example, but they have data going back to before 1986, and different divisions like by zip code or state.
There are also a lot of rows of data, but after filtering the data or narrowing the scope to be only a certain state would lower the amount of rows a lot.

County Business Practices

This visualization compares data from the U.S. Census Bureau’s County Business Patterns for 2020 against a separate dataset of scores. Using a D3.js-based web application, it loads two CSV files from GitHub Gists and displays their parsed contents as JSON in two separate `<pre>` elements. The code leverages d3’s `csvParse` and `select` APIs within a state-driven render loop, fetching and updating data asynchronously to showcase raw data from the Combined Statistical Areas. It offers a minimal, text-based view of the structured datasets.

Transforming CBP Data

This example transforms U.S. Census County Business Patterns data for New York State, identifying the economic sector with the most establishments in each county. The visualization fetches county-level records via the Census API, filters out the “Total for all sectors” row, and uses `flatGroup` and `maxIndex` to summarize the dominant sector per county. The resulting JSON summary is displayed as text in a `pre` element, with all data processing handled through D3 v7 utilities like `csvParse`, `rollup`, and `bin`.

Parse socioeconmic_data_states_2019-2010.csv

This example parses a US Census socioeconomic dataset covering states from 2010 to 2019, displaying basic file statistics such as size in kilobytes, row count, and column count. It shows how to load and inspect a CSV file using `d3.csv`, then formats the results into a text message rendered in a large `<pre>` element. The code also includes commented alternatives using `fetch` with `async`/`await` and `d3.csvParse` for comparison. The data source is a remote CSV file hosted on GitHub Gist, containing quantitative census attributes like employment, occupation, industry, and poverty rates.

D3 Scatter Plot Socioeconomic

This scatter plot visualizes socioeconomic data from the US Census 2019-2010 American Community Survey, displaying employment counts by state and NAICS sector for 2019. The visualization uses D3 v6 with SVG rendering, employing `d3.csv` to load the data and `d3.scaleLinear` and `d3.scalePoint` for positioning. Points are plotted using the `Estimate` values for employed civilians, with `d3.axisLeft` and `d3.axisBottom` providing labeled axes. User interactions are not apparent, as the code focuses on static scatter plot generation.

Loading and Parsing CSV Data for Bee Colony Census Data by County

This example loads a CSV file of bee colony census data by county and displays a summary of its size in the browser, showing the file’s kilobyte count, number of rows, and number of columns in large text. It demonstrates both `d3.csv` for parsing and an alternative async/await approach with `fetch` and `d3.csvParse`. The data, sourced from Data World via a GitHub gist, contains agricultural district and colony value columns, but no chart is rendered—only the dataset’s structural metrics are presented.

Parse BFS_national_by_month_2004-2021.csv

This example loads a national Business Formation Statistics dataset from 2004 to 2021 and verifies its contents by displaying the file size, row count, and column count. The code computes the size in kilobytes from the formatted CSV text and counts rows and columns from the parsed data. It uses the D3 v5 library’s `d3.csv` and `d3.csvFormat` methods to fetch and inspect the data, with an alternative approach using `fetch` and `d3.csvParse` shown in comments. The visualization itself is not yet rendered, only the parsed dataset metadata is presented.

Loading US Employment/Unemployment Data

This example demonstrates loading and displaying US employment and unemployment data from a CSV file. It first shows a raw JSON representation of the data, initially indicating a "LOADING" state before fetching the dataset from a GitHub Gist. Once retrieved, it parses the CSV string using D3's `csvParse` method, converting numerical fields from strings to numbers and handling footnotes. The visualization uses the D3 v7 library to manage the asynchronous data-fetching workflow, updating the displayed content via a state management system. The data originates from the USA Bureau of Labor Statistics, covering civilian noninstitutional population employment status since 1940.

Dataset from Center for Societal Benefit through Healthcare

This example maps county-level health and sociodemographic data from the Center for Societal Benefit through Healthcare’s CSV files. It uses D3.js to draw an interactive choropleth of the United States, with counties colored by a selected risk measure such as COVID-19 cases or chronic disease prevalence. A brush and zoom tool enables panning and scaling via d3.zoom. Hovering over a county updates a tooltip with its values, while a legend and dropdown filter allow users to switch between indicators like obesity, insurance coverage, or healthcare provider access.
