Web applications are normally data-driven and quite often the need occurs to imagine this data. That’s where charts and graphs came in. They make it simpler to convey information, as well as demonstrating correlations or statistical romantic relationships. Information presented by means of a chart or a graph is also easier for a non-native loudspeaker to understand. Within this tutorial, we’ll understand how to imagine data in a Vue task.
For this, we’ll be using the popular D3.js collection, which combines powerful visualization components and a data-driven method of DOM manipulation. Note: the code because of this tutorial can be found on GitHub. As you can continue reading the project’s home page, D3.js is a JavaScript collection for manipulating documents predicated on data.
D3 can help you bring data alive using HTML, SVG, and CSS. Its focus on web standards gives you the entire capabilities of modern web browsers without tying yourself to a proprietary construction. Whereas most people will refer to D3.js as a data visualization library, it’s not. D3 is more of a framework composed of different parts – such as jQuery parts (that assist us to select and change DOM elements), Lodash parts, computer animation parts, data analysis parts, and data visualization parts.
In this tutorial, we’ll be dealing with the visualization aspect of D3. You want to create an app that lets users visit a repo on GitHub, then get a visual representation of issues opened up before the week that are still open. This tutorial assumes you have an operating knowledge of Vue. Previous knowledge of D3.js isn’t required, but if you’d like to quickly get up to acceleration, you might read our D3 by example tutorial.

You’ll also need to have Node installed on your system. You can do this by downloading the binaries for your system from the official website, or using a version manager. I prefer creating new Vue projects using Vue CLI. The CLI provides a nice folder structure for placing different sections of the code, such as styles, components, etc.
Note: while creating a fresh project using Vue CLI, you’ll be prompted to choose a preset. Despite the fact that this is a simple application that doesn’t have many working parts, we’ll still take the components approach of dumping all the code inside the App instead.vue file. We’re going to have two components, the App element and a Graph component that we’re to produce yet.
