Mirjam Leunissen is a data journalist and visualization specialist with a scientific brain and a passion for visual storytelling.
I design and develop data visualizations for the web. On all topics, from the very small and personal, to big societal issues. Starting with my own data and analysis, international open data or your proprietary research. And always selecting the form that best gets the point across, from stand-alone site to web animation or social media imagery. In addition, I share my knowledge and inspire others through training and public presentations.
First of all, I sketch, discuss, and refine my design concept and prototypes, using digital pen and paper or Adobe XD. I then bring my ideas to life with a wide variety of tools for data wrangling, storyboarding, visualization and interactive storytelling. Besides R, the Adobe Creative Cloud and HTML5/CSS3 these frequently include:
I experiment with many different formats to make topics more tangible and to let readers explore and experience certain issues for themselves. If you don’t speak Dutch, you can view my projects with Chrome page translate.
I developed an intuitive, visual simulation to illustrate the main characteristics of a viral outbreak. It lets users see for themselves what challenges the corona pandemic poses, why we went into a lockdown and what it takes to escape from it again.
National Health Institutes interviewed nearly half a million people in The Netherlands about their health, from chronic illness to smoking and depression. I developed an interactive map, which shows the regional patterns and lets the user zoom in on specific neighborhoods.
A fellow data journalist identified thousands of YouTube channels with a far-right ideology. I created a visual tour through this universe, showing how the channels cluster around topics like nationalism and anti-feminism, and how they lead viewers to increasingly extremist content.
I made a scroll-animated globe, which takes the readers on a journey past a large variety of open-source data, e.g., on population growth, poverty, and land use. It fuels the question of whether we can sustainably feed the expected global population of 10 billion people.
I am an Amsterdam-based data journalist and visualization specialist with a PhD in physics and chemistry. I spend most of my time at national newspaper ‘de Volkskrant’, but I also work with a variety of other people, including government, academic institutions and companies.
I tell data-driven stories and convert complex information to actionable insight. Because the best visualizations readily reveal the big picture, the important patterns and the remarkable anomalies. My user-centered designs do so in an intuitive and engaging way.
Just tell me what you are looking for! I am also happy to present and inspire with the best examples from the field or to share my knowledge of best practices in data visualization and creative design thinking.
