The example processes a pipe-delimited CSV file containing customer meter readings, using Ruby’s CSV library to parse each row. It calculates statistics on unique customers, electricity versus gas usage, and monthly average consumptions. The code also groups customers by their number of meter readings and prints these distributions in formatted text tables. Active Support’s inflector and Date::MONTHNAMES are used for label handling, while a Set tracks unique customer IDs. The output is a plain-text summary of computed statistics, with no graphical visualization.

Gist 8522961

This visualization demonstrates the distribution of utility customers by the number of meter readings they have, broken down by energy type. It shows how many customers fall into each category of meter-reading frequency, allowing comparison between electricity and gas customers. The Ruby code parses a pipe-delimited CSV file using the `CSV` library, structures the data with a `Customer` struct, and computes statistics through a `Statistics` module. The chart is rendered as text-based output, using string formatting and the `Date::MONTHNAMES` constant to display monthly averages, with results centered using the `center` method for alignment.

Gist fdfdd728007f46922fdc

This example demonstrates how to read and write text and CSV files in Ruby, using the CSV library. It reads names from a text file into an array, prints the array, and then appends the word "likes" to each name before saving the result to another text file. The code also writes the original names to a CSV file. This is a file-processing utility rather than a data visualization, focusing on data manipulation and storage.

Parse electricAccountsData.csv

This example parses a CSV file containing household electric consumption data, showing the file size in kilobytes, row count, and column count. Using D3 v5, the code loads the dataset via the `d3.csv` method and formats it with `d3.csvFormat`. It also demonstrates alternative loading approaches commented out, including `fetch` with `async`/`await` and a nested promise chain. The data source is a remote GitHub Gist containing three electric accounts with attributes like total kilowatt-hours, utility charges, and net meter credits.

Parse and process CSV data

This example demonstrates how to parse and process CSV data, displaying the file size, row count, and column count of a remote CSS-named-colors dataset. A large <pre> element shows these three metrics. The primary approach uses the D3 v6 `csv` method to fetch and parse the data, then `csvFormat` and `data.length` to compute metrics, while a commented alternative shows an equivalent implementation with `fetch`, `csvParse`, and async/await.

Loading and Parsing Bank Customers Dataset

This example shows the basic structure of a bank customer dataset by displaying three summary statistics: file size in kilobytes, row count, and column count. It loads a CSV file from a GitHub gist using `d3.csv` and parses the data, then formats the metrics with `d3.csvFormat` and `Math.round`. The results are rendered as large text inside a `<pre>` element. The visualization relies on D3 v5’s promise-based loading API to handle the asynchronous data fetch.

Gist 585199

This visualization loads an external CSV file and parses its rows into JavaScript objects, mapping each column name from an array to the corresponding values in each line. It handles quoted fields that contain commas by merging split segments until the quote count is even, and it logs warnings for malformed lines that do not match the expected number of columns. The example demonstrates a reusable CSV-asynchronous-loading helper, but does not show any charting, layout, or rendering code beyond the data preparation stage.

Csv Parse

This example demonstrates how to fetch and parse a CSV file containing named CSS colors, then calculate and log basic statistics about the dataset. It uses the Fetch API to retrieve the remote CSV file and d3.csvParse to convert the raw text into an array of objects. The code counts the number of rows and estimates the file size in kilobytes, though the results are not displayed visually. The example highlights the basic workflow of loading tabular data with d3 v5 in a minimal HTML page.

Fork of CSV Dataset Template - Computer Network Traffic

This example displays the raw JSON structure of the first record from a CSV dataset of computer network traffic, showing fields for date, local IP number, remote ASN, and flow count. It loads the CSV data using a custom parsing function, converts the numeric string fields to numbers, and uses JavaScript string interpolation to render the data within a `<pre>` tag. The visualization is minimal, focusing on the data's shape rather than its temporal trends or correlations.
