Oscillate between two values
function oscillate(from, to, duration) {
return x => from + (to - from) * (0.5 - 0.5 * Math.cos((2 * Math.PI / duration) * x))

i(now)
Plot.line(d3.range(0, 1e4, 10), {x: d => d, y: d => i(d)}).plot({width})
oscillate2 = (n) => -Math.abs(2 * (n % 1) - 1) + 1;
Plot.line(d3.range(0, 3.1, 0.1), {x: d => d, y: d => oscillate2(d)}).plot({width})

Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
