This example demonstrates the process of transforming a Healthy People 2020 dataset through binned aggregation and summary statistics, showing computed averages of final year estimates grouped by population group. The visualization begins by fetching a CSV file via a GitHub gist URL, then uses d3.csvParse to load the data. It employs d3.flatRollup, d3.sum, and d3.bin to calculate aggregated values and create binned distributions across numeric fields. The output displays the raw parsed data as JSON text using d3.select and .join.

Fork of Transforming Data

This example demonstrates the results of applying D3 data-transformation APIs to a dataset of Human Development Index (HDI) indicators for countries across multiple years. It shows how aggregation methods like `flatRollup`, grouping via `flatGroup`, and `bin` summarize and reshape the raw CSV data into compact summaries. The visualization outputs the transformed results as formatted JSON text using `select` and `join`, displaying counts, averages, or binned ranges depending on the uncommented transformation. The code relies on D3 v7 functions such as `csvParse`, `bin`, `min`, `max`, and `extent` to process the data.

Fork of healthy people 2020

This fork of Healthy People 2020 visualizes final health-status progress for population subgroups defined by race, income, education, disability, and geography. It uses a data-driven approach with D3.js v7, fetching a CSV from CDC’s data portal to display objective outcomes. The code leverages `d3.csvParse` to parse the dataset, then renders state data inside a `<pre>` element for inspection.

Transforming Data

This visualization demonstrates data transformation techniques, specifically binned aggregation, using the D3.js library. It loads S&P 500 stock data from a CSV file and applies various D3 operations such as `flatGroup` and `flatRollup` to summarize the data. The example groups the dataset by industry and displays the resulting summary as a JSON object on the page. The code also includes commented-out examples of other transformations, such as computing minimum, maximum, extent, and creating binned histograms. The final output shows the transformed data structure in a simple text format.

Fork of Transforming Data

This example illustrates data transformation techniques on the classic Iris dataset, showing how to summarize raw CSV data into aggregated statistics. The visualization computes the average sepal length for each iris species using d3.flatRollup and d3.sum, then renders the resulting summary as a JSON object in a preformatted text block. The code demonstrates the use of d3.csvParse for data loading and d3.select for DOM manipulation.

Transforming Data_NH

This visualization demonstrates binned aggregation and data transformation techniques using D3.js (v7). It loads solar energy data from a CSV file and computes the average maximum wattage per site address using `flatRollup` and `sum` functions. The resulting summary is displayed as formatted JSON text within a `<pre>` element, showcasing how raw tabular data can be programmatically summarized. The example uses D3's `csvParse` for data parsing and `select` for DOM manipulation.

Fork of Data transformation health expenditure

This visualization explores personal health care spending by age, gender, and payer source, using data from the Centers for Medicare & Medicaid Services. It shows per capita expenditure differences between males and females across age groups (0-18, 19-64, 65+) for selected years from 2002 to 2014, addressing questions about spending by gender and population percentages. The code loads a CSV via `d3.csvParse` and `fetch`, then processes data with `d3.flatRollup` and `d3.sum` for aggregations. The current render displays raw JSON output via `d3.select` and `join`, with the full interactive visualization logic still under development.

Fork of transformation health expenditure Year Column

This visualization examines personal health care spending by age group, gender, and payer, using data from CMS National Health Expenditure Accounts. It displays per capita expenditure differences between males and females across age cohorts (0-18, 19-64, 65+) for years 2002–2014. The code loads a CSV via `d3.csvParse` from a GitHub gist, then uses `d3.flatRollup`, `d3.sum`, and `d3.group` to aggregate and summarize the filtered records, outputting computed averages and category sets as JSON text via `select().join()`. Data sets include payer, service type, age group, gender, and year.

Fork of Data Table Summary

This fork of a Data Table Summary uses D3 v5 to load a 2018 United Nations population dataset from a CSV file and display basic summary statistics. The visualization prints the total number of rows, columns, and file size in kilobytes, followed by the first ten rows of data as JSON. The code demonstrates D3’s `csv` and `csvFormat` functions for data parsing and formatting, presenting results in simple text blocks on a black background.
