Data Visualization Tools

Data / Information Visualization Tools

Note: I've edited the page and restructured the list of links - ideally some of them should be added under the relevant existing pages here on the toolkit.
Page also needs examples and tips, will see if I can find some but please feel free to jump in!

Brief Description

Creating visualizations of data can offer another way of communicating and sharing that data with others. Visuals can stimulate conversation and meaning making around data that is different from simply presenting the textual or numerical data. This is especially important when working across cultures and languages. Please note that visuals carry as much cultural connotation than any other communication form, so this does not mean that a visual will necessarily have a universal interpretation!

Data visualization closely relates to information graphics (infographics). Even if these terms are often used interchangeably, it is possible to identify some differences between the two.

According to a recent article from Idealware, "data visualizations take complex sets of data and display them in a graphical interface – for example, in a chart or on a map – which allows the user to gain deeper insight into patterns and trends. Infographics use data visualizations in concert with text and other tactics to tell a story, make a point or communicate a concept.

However, both allow to make a different use of the data you have available and transform them into a compelling presentation or powerful story. These types of products are highly share-able on social media channels and social networks and, when well done, they can give more mileage to your content.

When to use

  • To analyze your data
  • To convey complex data and abstract information in a digestible format
  • To visualize information, systems, networks and flows
  • To illustrate timelines and relationships
  • To tell your story effectively and reach your different audiences
  • To make your message more compelling

How to use

The practical use differs very much according to the tool you are using; some applications are web based only while other can be downloaded on your own laptop.

Tools to use

Many different tools can be grouped under the heading of data and information visualization. In the list below, we try to organiza the tools according to the contebt object we can produce, or the type of data and information visualized.

Examples & Stories

  • For a great example how data can be visualised take a look at the Ted Talk from Hans Rosling (founder of Gapminder): "It's a real tour de force of amazing graphic animations that deconstructs a few development myths and challenges many assumptions that, in Rosling's view, stem from data being difficult to access. Perhaps more importantly for the purposes of knowledge management for development, he forcefully makes the point that the fact that data are buried in a variety of restricted access databases and/or are provided without any user-friendly graphic interface seriously hampers policy formulation and development work on the ground."
  • DevInfo, offers a good data visualization toolkit which makes it easier to interactively explore the data.
