Data Dashboards with JavaScript shows how to data dashboards with JavaScript.

You'll learn how to build a data dashboard using charting library Chart.js, mapping library Leaflet and UI library React. View the dashboard you'll learn to build.

Some of the topics covered are:

• creating a web application with JavaScript
• the Vite build tool
• making a chart with Chart.js
• using Tidy.js to process data
• styling Chart.js charts, including dark theme, multi-line charts and stacked bar charts
• introduction to Leaflet for creating maps
• how to make a data-driven map with Leaflet
• introduction to React
• how to make a data dashboard using React, Chart.js and Leaflet
• how to create an API for the dashboard
• how to deploy the dashboards
• how to transform the data from the UK Government into a JSON file

Some of the chapters include exercises and solutions.

There's a code download containing ten examples, including multiple Chart.js examples, a data-driven Leaflet map, a data-dashboard, a client-server data dashboard and a data-wrangling example.

To get the most out of this book you need to be familiar with HTML, SVG, CSS and JavaScript. If you need to get up to speed with these languages I recommend my book Fundamentals of HTML, CSS, SVG & JavaScript for Data Visualisation. I've bundled both books together at a reduced cost (visit bundle).

You also need a text editor (such as VS Code) and an installation of Node.js.

This book uses ES Modules and modern build-tools throughout so you'll learn about current technologies.

I've also published Visualising Data with JavaScript which shares some chapters with this book but doesn't cover data dashboards or React. Instead it has chapters on D3 and Data Stories.

This book covers the fundamentals of HTML, SVG, CSS and JavaScript for visualising data.

If you're wanting to learn D3.js (or other JavaScript visualisation libraries) and need to get up to speed with HTML, SVG, CSS and JavaScript, this book is ideal. It goes through the basics of these languages, and gives a good foundation for learning libraries such as D3.js.

It's also useful if you're coming from a language such as Python or R and use tools such as Dash and Shiny. If you're wanting to customise your web applications and CSS and JavaScript are a stumbling block then this book should help.

This book doesn’t assume prior knowledge of HTML, SVG, CSS and JavaScript but it’ll be helpful if you’ve some coding experience. Being familiar with a text editor (or IDE) will also be helpful.

It’s by no means a comprehensive tutorial on HTML, SVG, CSS and JavaScript. You’d need a much bigger book for that. Think of this book as presenting the minimum of what you ought to know if you’re wanting to work with web based data visualisations.

This book is an ideal foundation for D3 Start to Finish.
