@visx/mock-data

The @visx/mock-data package is here to help you test out your graphs.

Installation

npm install --save @visx/mock-data

Generators

Generators can create simple generic data for you like this:

import Mock from '@visx/mock-data';
const points = Mock.genRandomNormalPoints();

Mock.genRandomNormalPoints()

Returns a series of random normal x,y points.

Mock.getDateValue(n)

Generates n date values an hour apart from each other starting with the current time.

Mocks

Mock are essentially a bunch of data dumps that you can use like this:

import Mock from '@visx/mock-data';
// or import { cityTemperature } from '@visx/mock-data';
const data = Mock.cityTemperature;
