Write some JS code to draw the polar chart

The preparations are all done and it is time now to make the JavaScript-based polar chart show up on the canvas! 4. Now, to properly add this data to the chart, I create an array with the category name as the x parameter, as we are plotting on the X-axis, and the measure of each of the categories as the value parameter. To get a dataset for my future polar chart, I filtered DVS’s Data Visualization Census Survey 2020 data and identified the 15 most commonly used technologies as answered by the respondents. All the JS polar chart code will come here. The library is modular, and for the polar chart, all I need is the handy core and polar modules. Here, I am working with An圜hart, so I will include the required files from its CDN. Next, in the section of the page, I reference the specific scripts of the charting library being used.

2. Reference the required JavaScript files Also, the width and height of the block are specified as 100% to make the polar chart render over the whole page. Width: 100% height: 100% margin: 0 padding: 0 Īs you see the element is given an id so that I can refer to it later in the code. To begin with, I create a basic HTML page and a block element that will hold the polar chart: Join me in following these steps to make an awesome interactive JavaScript-based polar chart visualization! 1.

Reference the required JavaScript files.

Generally speaking, it is possible to split the entire process of creating any JS graph including a polar chart into four fundamental steps or stages. Also, it is a great library to start with because of a lot of examples and good documentation.

Such libraries are equipped with pre-written code for basic functions, which makes it easier and quicker to create a data visualization.įor this tutorial, I’ve picked the An圜hart JavaScript library since it is simple to use, flexible, and free for non-commercial use.

To create a polar chart here, I will use a JavaScript charting library.

Take a sneak peek at what the final JavaScript polar chart will look like:īuilding JavaScript Polar Chart in 4 Simple Steps So here, I will produce a JS polar chart that plots the top 15 ones, making up a cool illustrative real-world example. In particular, I wanted to look at the most popular technologies used for data visualization based on the responses. In this tutorial, I will build a column polar chart, with the bars growing from the center of the diagram to represent values with their length.ĭata Visualization Society (DVS) conducts an annual State of the Industry survey of data viz practitioners, and I thought it could be a great opportunity to play with some of its latest data. It can also work well to visualize some sorts of categorical data for comparisons, which is exactly the case I want to demonstrate now.

Well, I am going to debunk this myth right now! Let me show you how to easily visualize data in a beautiful interactive JavaScript Polar Chart.įundamentally, a polar chart is a variation of a circular graph drawn with polar coordinates. Polar charts often look impressive, which makes some people think that creating them is a tricky process demanding plenty of skills and expertise.
