How can data visualisations on the web be improved?
More general I feel like most people just go for the bar or line chart even when other (simple) charts might show the insight that I think they want to convey in a more effective way. Think of charts such as slope charts, sankey diagrams or scatterplots, think that more and more tools are able to create. On the web specifically, I see a lot if "useless" interactivity actually (such as bar charts that have an axis where on a hover you see the value in a tooltip, even though you can read that from the axis...). Integrating interactivity can be an expensive part, time-wise, and just because you can do it these days, doesn't necessarily mean you should.
What can people expect to take away from your talk at Pixel Pioneers?
How to actually think about going beyond those bars and lines. How to go about making a chart that is customised to your data and showing the insights that it holds in an effective and engaging manner.
Why did you decide to go freelance, and how has your life changed since?
After a year working for one company I found out that I missed the diversity that I used to have in my previous job as an analytics consultant: different data, different problems, different industry every few weeks/months. So I decided I wanted to freelance as well, so I would get that diversity back again. That I could collaborate with people and work with companies that hold data that I'd love to dig into. It's been really great, although I've only been freelancing for three months. But I'm working with companies now from Google to a small company that does brain scans to see changes in emotions on how people perform tasks on the web, which really helps my creativity, this diversity.
What are you working on at the moment?
I've just finished a really fun project for Google. I was given complete freedom which was awesome (and intimidating at the start) as long as it used Google data. I chose to dig into Google Translate data. This was driven by being a Dutch native, but 95% of my day is English, so I find myself translating words often. I was wondering how other languages translate words as well. Do German speakers want other words translated into English than Spanish speakers? Spoiler: yes, they do! I created a page that guides the viewer to the insights that I found with several (interesting I hope) visualisations.
