Tiny Linked Charts for Svelte

This is a library to display tiny bar charts. These charts are more so meant for graphic aids, rather than scientific representations. There's no axis labels, no extensive data visualisation, just bars.

Demo and Docs: https://mitcheljager.github.io/svelte-tiny-linked-charts/

Installation

Install using Yarn or NPM.

yarn add svelte-tiny-linked-charts --dev

npm install svelte-tiny-linked-charts --save-dev

Include the chart in your app.

import { LinkedChart, LinkedLabel, LinkedValue } from "svelte-tiny-linked-charts"

<LinkedChart />
<LinkedLabel />
<LinkedValue />

Supply your data in a simple key:value object:

let data = {
  "2005-01-01": 25,
  "2005-01-02": 20,
  "2005-01-03": 18,
  "2005-01-04": 17,
  "2005-01-05": 21
}

<LinkedChart { data } />

Or if you prefer supply the labels and values separately:

let labels = [
  "2005-01-01",
  "2005-01-02",
  "2005-01-03",
  "2005-01-04",
  "2005-01-05"
]
let values = [
  25,
  20,
  18,
  17,
  21
]

<LinkedChart { labels } { values } />
