Tutorial & D3.js
I’ve already shown the diversity of using gradients in data visualization in several other blogs in this series. But you don’t even have to use gradients as something that runs smoothly from one color to another. They can be very handy for abrupt changes as well. The first time I ended up using this technique was when I became interested in the popularity of baby names.

Just over a year ago I posted a blog about the Gooey effect that makes it seem as if things (SVGs) start sticking together once they come close to each other. As if they are water droplets merging together. For my preparation for the “SVGs beyond mere shapes” talk I returned to the gooey effect and in this blog I’d like to teach you a few more techniques to take full use of the power of the gooey.

In this blog, I’ll show you how to add a color gradient to the chords of a d3.js Chord Diagram. This comes in handy when there is no net difference in the chords. But you can apply the technique to any gradient that you want to orient based on data. We’re going to look at the collaborations between Avengers. With all those cameo’s happening in the MCU, I wanted to know how often two Avengers had appeared in a movie together. This results in a symmetrical dataset since, if Thor appeared in a movie together with Hawkeye, the reverse is true as well.

Today it’s time for a short blog about a very subtle effect that can add a bit more pizzazz to your visualization. It’s definitely not something that will suit a business/no-nonsense chart. But then again, if you only make those kinds of charts, I feel that doing data visualization is definitely less enjoyable than if you try to have some fun with your creations every now and then. So let’s start by adding a bit of glow to our shapes!

In the past few weeks, several tutorials about SVG gradients in data visualizations have come to pass already. But those were mostly focusing on creating one gradient. In this tutorial, I want to show you how you can create a gradient for each of your datapoints. And how to adjust each of these gradients using some aspect of your data, so each gradient will become unique.

In this short tutorial I want to introduce you to those wonderful color blending modes that you have (in Photoshop for example) where two colors overlapping each other can create another color. I actually started out trying to recreate this effect with SVG filters. But then I found out that it be done with just two lines of CSS.

We’re picking up right where I left you in my blog on Hacking a Chord diagram to visualize a Flow where I turned a Chord Diagram into a more circular flow diagram. Even with the chords now having been turned into a “bat-plot” I still wanted to emphasize more that we were dealing with a flow from left to right, from Education to Occupation. So, I thought, why not try to use a gradient and animate a movement/flow towards the right.

A filter that can create a subtle but interesting effect has to do with motion blur. The faster and closer to us things move in the real world, the more blurred they appear. And with the right filter, you can recreate this effect on the screen as well.
