Guidance: Tools for Data Visualisation

See below for Hindi, Vietnamese, Bangla, Thai and Bahasa Indonesia versions.

Data Visualisation has been a key feature of the COVID-19 pandemic. As we all work together to ‘flatten the curve’, charts, graphs and maps are a key feature of our television screens and social media feeds. With more information at our fingertips than ever before, the importance of data visualisation has never been greater than it is right now.

We’ve seen some great examples from the BBC, Financial Times and The New York Times has been mapping the spread of the virus from its early days, changing what it maps and how it maps as the pandemic unfolds.

What is data visualisation?

Data visualisation is the act of taking information, or data, and explaining it by using visual tools such as a map or graph or other images. Data visualisations can help you translate a flood of COVID-19 information and deliver it in a format your audience will understand. They are creative, eye-catching, and make it easier for the human brain to process complex information.

What makes good data visualisation?

Data visualisation takes more than simply adding an image or a graph to your stories. A good data visualisation is the combination of: Data, Design, Story, and Sharability.


Start with good quality data: Has your data been cleaned to make sure there are no mistakes, double-ups, or misspellings? Is it from a reliable source?

Make sure you understand exactly what is being counted. There are lots of COVID-19 numbers floating around and it’s important to understand what they mean and what is being measured.

Use relevant comparisons: Comparisons can be a great way to give context to data. Is this a big change? How does this data compare to my context? But make sure you use a fair comparison. For example, comparing the COVID-19 infection numbers in a big city compared to a remote region with a low population doesn’t make a lot of sense. Whereas comparing two cities of a similar size might tell a more useful story for your audience. Otherwise, you can use rates, which calculates the number in relationship to the population size.


Clear headings and keys: While the image does most of the storytelling, don’t forget to clearly label what the story is about. A good heading will also work to draw attention to your visuals.

Always include the source of your data at the bottom of your visualisations with the name of the organisation that published the data and a link to where you found it.

Be creative – but clear: Having too many visual elements (colours, fonts, styles) can detract from the message you’re trying to get across. Visualisations are all about making data accessible to a broad audience. People tend to blame themselves when they have difficulty interpreting a graph. But in most cases, it’s not people’s fault, it’s the design’s.


Think about how the visualisation contributes to the story you are trying to tell.

Pick the right format: Bar charts are good for comparisons, line charts show a trend over time, while pictograms are fun and engaging. Make sure you pick a format that adds, rather than detracts from your storytelling. See here a list of the 17 most common types of data visualisation and their benefits.


Good data visualisation gets people talking about your story! Good quality content is the first step, but you should also consider what file type the data visualisation uses. A GIF or animation for example, provides the opportunity of moving content that performs really well on social media. Consider showing graphs grow over time, or animations paired with music or sound. Link any images back to the article so that once you have the reader’s attention, they can easily find the full story. Information is Beautiful has lots of great examples of visuals that communicate and inspire.

Make sure your visualisation has a headline that emphasises what is newsworthy in the visualisation. Don’t assume that your audience will instinctively understand why the data is important. Audiences have very different levels of data literacy, time and attention!

The good news is there are lots of great free tools available online that will help you create engaging content from day 1.
