Radial Line Chart
license: mit

A radial line chart showing how Twitter's stock has changed over the last year - from July 2016 to July 2017. Not particularly useful - both axes need work to improve legibility (and I'm not sure using d3.extent is a good idea here).

(function(global, factory) {
typeof exports === "object" && typeof module !== "undefined" ? factory(exports, require("d3-scale")) :
typeof define === "function" && define.amd ? define(["exports", "d3-scale"], factory) :
(factory(global.d3 = global.d3 || {}, global.d3));
}(this, function(exports, d3Scale) {
'use strict';
function square(x) {
return x * x;
}
function radial() {
var linear = d3Scale.scaleLinear();
function scale(x) {
return Math.sqrt(linear(x));
}
scale.domain = function(_) {
return arguments.length ? (linear.domain(_), scale) : linear.domain();
};
scale.nice = function(count) {
return (linear.nice(count), scale);
};
scale.range = function(_) {
return arguments.length ? (linear.range(_.map(square)), scale) : linear.range().map(Math.sqrt);
};
scale.ticks = linear.ticks;
scale.tickFormat = linear.tickFormat;
return scale;
}
exports.scaleRadial = radial;
Object.defineProperty(exports, '__esModule', {value: true});
}));
