# JavaScript COVID-19 Tracker Chart

![JavaScript COVID-19 Tracker Chart](racingBars-darkGold.png)

This demo application belongs to the set of examples for LightningChart JS, data visualization library for JavaScript.

LightningChart JS is entirely GPU accelerated and performance optimized charting library for presenting massive amounts of data. It offers an easy way of creating sophisticated and interactive charts and adding them to your website or web application.

The demo can be used as an example or a seed project. Local execution requires the following steps:

- Make sure that relevant version of [Node.js](https://nodejs.org/en/download/) is installed
- Open the project folder in a terminal:

npm install # fetches dependencies
npm start # builds an application and starts the development server

- The application is available at _http://localhost:8080_ in your browser, webpack-dev-server provides hot reload functionality.

## Description

_Also known as Bar Graph, Column Chart or Column Graph_

Showcase of LightningChart JS Bar Charts in a _Racing Bar Chart_ context, to visualize tracking of the Co-Vid 19 virus.
Tha data (country, history of cases) that is taken from API (https://coronavirus-tracker-api.herokuapp.com/confirmed)
In setInterval loop data is sorted by total COVID cases per each day and top 20 cases added to
the bars series in format `{ category: string, value: number }`.

Sorting and animations are built-in to the chart feature, which makes the application code minimal and simple to maintain.
