El Patrón de los Números Primos: Prime Number Patterns
by Jason Davies. For each natural number n, we draw a periodic curve starting from the origin, intersecting the x-axis at n and its multiples. The prime numbers are those that have been intersected by only two curves: the prime number itself and one. Below the currently highlighted number, we also show its sum of divisors σ(n), and its aliquot sum s(n) = σ(n) - n, which indicate whether the number
Parallel Sets
A visualisation technique for multidimensional categorical data. Titanic Survivors Explanation For each dimension (Survived, Sex, Age and Class), a horizontal bar is shown for each of its possible categories. The width of the bar denotes the absolute number of matches for that category. Starting with the first dimension (Survived), each of its categories is connected to a number of categories in t
Word Cloud Generator
Paste your text below! How the Word Cloud Generator Works The layout algorithm for positioning words without overlap is available on GitHub under an open source license as d3-cloud. Note that this is the only the layout algorithm and any code for converting text into words and rendering the final output requires additional development. As word placement can be quite slow for more than a few hundre
Animated Bézier Curves
These animations illustrate how a parametric Bézier curve is constructed. The parameter t ranges from 0 to 1. In the simplest case, a first-order Bézier curve, the curve is a straight line between the control points. For a second-order (quadratic) Bézier curve, first we find two intermediate points that are t along the lines between the three control points. Then we perform the same interpolation
