This example demonstrates the simple concatenation of multiple CSV files into a single output file, combining rows from all input files without any transformation or filtering. The script uses the `csv.reader` and `csv.writer` APIs from Python’s standard library to parse and write each row, while the `glob` module collects every `.csv` filename in a specified directory, and `os.chdir` changes the working directory to that folder. All rows are appended into a flat list, then written to a designated output path. The visualization shows the raw data-merging process, not a graphical chart, and relies solely on file I/O and CSV handling.

Fetching CSV

This example demonstrates loading three CSV files in parallel using the Fetch API and Promises. It visually presents the result of summing the numbers from each file, updating the text “1 + 2 + 3” with the computed total. The code relies on `fetch` to retrieve each CSV and `d3.csvParse` from d3-dsv to parse the responses, then combines them with `Promise.all`. The final sum is displayed in an HTML heading, showing asynchronous data loading and aggregation.

This example demonstrates how to load and combine multiple CSV files using D3 v5’s Promise API. It shows the parsed contents of two separate CSV files (file1.csv and file2.csv) logged to the browser console after both have loaded successfully. The code uses `d3.csv()` to fetch each file and `Promise.all()` to wait for both requests before logging the resulting arrays of objects. The page displays a simple heading and relies entirely on console output for visualization, with no graphical rendering. The data source is the two CSV files, and the approach highlights asynchronous data loading in D3.

Data To Concatenate

This visualization demonstrates the process of reconciling two versions of a spatial dataset, showing how duplicate headwords with shared geographic coordinates are merged into a single canonical record. It displays a side-by-side comparison of the original data file, which contains separate entries for “Acre” and “Akko,” against a new file that concatenates them into one row with a joint headword. The visualization uses the processing library to read and parse both CSV files, comparing rows based on the Syriaca URI field to identify matches, then rendering the results in a tabular layout. It relies on core Java file I/O and string manipulation methods to handle the data transformation, with no external charting libraries involved.

Loading and Parsing CSV

This example demonstrates reading a raw CSV file from a GitHub Gist and logging its contents to the browser console. The page uses the Fetch API within an asynchronous `fetchText` function to retrieve the text from the specified URL, then displays the raw CSV data via `console.log`. The code highlights a basic loading pattern, contrasting it with a commented-out "pyramid of doom" approach that chains `.then()` callbacks. No CSV parsing or visualization occurs; the example focuses solely on data retrieval and output.

ReadBigCsvFile

This example shows how to process and split a large CSV file into daily chunks by grouping rows based on a datetime column. It uses pandas’ `read_csv` with `chunksize` to load data incrementally, then applies `Grouper` with a daily frequency to partition each chunk. The multiprocessing variant uses `ProcessPoolExecutor` and a dedicated writer `Process` that receives grouped data via a `Queue` for concurrent file output. All writes use `to_csv` with append mode, preserving existing files and headers across runs.

Gist 57367d54143770b7c1d534cbfe002cd9

This example shows a Python script that combines multiple video clips into a single montage, resizing each to a fixed 460×720 resolution and concatenating them in sequence. The code uses MoviePy’s `VideoFileClip`, `concatenate_videoclips`, and `write_videofile` functions, along with its `vfx` module for potential filters. It saves the final output with a timestamped filename and writes it as an MP4 using the H.264 codec. The rendering approach relies on MoviePy’s FFmpeg backend, processing clips in sequential order without additional data sources.

This example demonstrates how to load and parse two separate CSV files using D3.js v5, then combine them with a Promise.all to log their contents to the browser console. It shows the process of handling multiple asynchronous data sources and verifying their successful retrieval. The code uses `d3.csv` to fetch each file and `Promise.all` to wait for both to resolve, while also loading the Fetch API and promise polyfills for broader browser support. The visualization itself is minimal, with the output appearing solely as console messages rather than rendered graphics.

Loading and Parsing CSV

This example demonstrates the initial steps of loading and parsing CSV data for visualization, with a video embedded for reference. The page fetches a remote JavaScript file containing CSV data from GitHub Gist using the Fetch API, and logs the response to the browser console. However, the code is incomplete—it does not actually parse the CSV or render any visualization, despite the title. The example uses native browser APIs (`fetch`, `console.log`) within a bare-bones HTML page, highlighting the starting point of a data-loading workflow.
