JavaScript Leaders Demand Oracle Release the JavaScript Trademark
In an open letter, JavaScript community leaders urge Oracle to give up the JavaScript trademark, arguing that it has been effectively abandoned through nonuse.
The d3-scale package is part of the D3 (Data-Driven Documents) library that provides a powerful toolset for visualizing and mapping data. It offers a variety of scales for positioning and interpolating data, including linear, power, logarithmic, time, and ordinal scales. These scales can be used to transform data for visual representation in charts, graphs, and other data-driven visualizations.
Linear Scale
A linear scale maps a continuous input domain to a continuous output range. It is commonly used for quantitative data.
{"const scale = d3.scaleLinear().domain([0, 100]).range([0, 1]); const result = scale(50);"}
Ordinal Scale
An ordinal scale maps a set of named categories to a discrete range. It is useful for categorical data.
{"const scale = d3.scaleOrdinal().domain(['A', 'B', 'C']).range([0, 1, 2]); const result = scale('B');"}
Time Scale
A time scale is similar to a linear scale but is specifically for time-based data. It maps a continuous time domain to a continuous range.
{"const scale = d3.scaleTime().domain([new Date(2020, 0, 1), new Date(2020, 11, 31)]).range([0, 100]); const result = scale(new Date(2020, 5, 15));"}
Logarithmic Scale
A logarithmic scale is used for data that spans multiple orders of magnitude. It maps a continuous domain to a continuous range using a logarithmic transformation.
{"const scale = d3.scaleLog().domain([1, 100]).range([0, 1]); const result = scale(10);"}
Quantize Scale
A quantize scale maps a continuous domain to a discrete range. It divides the domain into uniform segments based on the number of values in the range.
{"const scale = d3.scaleQuantize().domain([0, 100]).range(['low', 'medium', 'high']); const result = scale(55);"}
Chroma.js is a small-ish zero-dependency JavaScript library for all kinds of color conversions and color scales. While it focuses on color manipulation, it offers similar functionalities to d3-scale when it comes to creating color scales.
Simple-statistics is a JavaScript library that provides descriptive statistics, regression, and other functions. It includes some scaling functions but is more focused on statistical analysis rather than the comprehensive scale generation provided by d3-scale.
Vega-scale is a collection of scales for encoding data visualizations. It is part of the Vega visualization grammar and provides similar functionalities to d3-scale, but it is designed to work within the Vega ecosystem.
