This example demonstrates how d3-format creates number formatting functions from format specifiers, testing values like 2.9971832 against descriptors such as `.1f`, `.2s`, and others. It also shows the default locale being overridden with French formatting rules, changing decimal separators to commas and thousands separators to periods. The code loads only the d3-format module and uses `document.writeln` to output results in a preformatted block. A commented section illustrates the same library working in Node.js.

d3js Exercice 1 - number formats

This example demonstrates how to format numbers in JavaScript using the d3-format module, highlighting the limitations of native floating-point arithmetic. It first shows the raw output of multiplying 0.1 by integers, then applies various format specifiers like `.1f`, `.2s`, and `.2s` with a custom French locale to control decimals, thousands separators, and SI-prefix notation. The code uses `d3.format` and `d3.formatDefaultLocale` from the d3-format v1 library, reading a hardcoded value (`x`) to illustrate different formatting outputs. The rendering approach is a simple HTML `<pre>` block with `document.writeln`.

Untitled

This example demonstrates how to format numbers with D3’s `d3.format` API from the `d3-format.v2` module. It creates two format specifications—a compact two-significant-digit format and a centered width-20 format—and outputs the results of formatting the number 12347 with each to the console. The code loads the D3 library from a CDN and executes the formatting calls directly in a script tag, showing the formatted strings as the primary output.

Hello VizHub

This example displays a large, centered numeric message generated from a simple calculation, formatted and rendered using D3.js v5 and ES6 modules. It shows how VizHub supports importing local modules and D3 API functions, with the message derived from a mathematical expression and formatted using the `d3.format` method. The page uses a CSS import for the Ubuntu font and a dark blue background to make the text prominent. The code demonstrates basic DOM selection, module exports, and D3’s number formatting in a minimal setup.

d3js Exercice 2 - Scales

This example demonstrates how d3.scaleLinear maps input values from a domain to a range, showing the output for inputs of 0, 10, and 20, then extending beyond the interval to reveal unbounded behavior. It then applies the clamp(true) method to the scale, which restricts outputs for out-of-range values like -10 and 200. Built with D3 v4, the code writes results directly to the document via document.writeln, and comments suggest experimenting with invert, power, log scales, or a color range.

Indian Number System Format

This example demonstrates a custom JavaScript function that formats numbers according to the Indian Number System, using commas in the thousands, lakh, and crore groupings. The left column shows positive values, while the right column displays their negative counterparts, using D3.js version 3.5.5 to append formatted text to the page. The code handles both integer and decimal numbers, including edge cases like 10,000 and negative inputs, as noted in the README.

Gist e75fdfd9429caf37873275cd41779b88

This example demonstrates a custom formatting function that inserts non-breaking spaces as thousands separators, a convention common in Finnish numeric formatting. The function, `spaceSeparateNumber`, iteratively processes the input number using a regular expression to identify digit groups, replacing them with a space between the leading digits and the trailing three-digit group. It relies on JavaScript’s string replacement and number-to-string conversion, without any external libraries. The visualization likely applies this formatting to numeric labels in a chart, ensuring readable, localized display of large values. The code focuses solely on text transformation, not on rendering or data binding, making it a standalone utility for formatting axis ticks or tooltip values.

d3js Exercice 2 - Scales

This example demonstrates the behavior of D3.js linear scales, specifically how they map input domain values to output range values. It shows the default scaling for values within the domain, then highlights what happens outside the interval, and finally illustrates the effect of the clamp method. The code uses `d3.scaleLinear()` with a domain of `[0, 20]` and range `[0, 1]`, logging results for various inputs including negative and oversized values. A second scale with `.clamp(true)` restricts outputs to the range. The visualization is purely text-based, using `document.writeln` to display computed values in the browser.

d3 experimental zone

The d3 experimental zone demonstrates how to begin working with D3 version 7, rendering a sequence of numbers from the array `[1,2,3,4,5,6]` directly into the page body. The example uses the `d3.select` API to target the body element and a chained `.Jenter` method to iterate over the data, with a `.text` callback displaying each value. The page is styled with a massive 13em font size, making the numeric output the focal point. This minimal setup illustrates the core selection and data-binding workflow in D3 while serving as a sandbox for experimentation.
