Making data visualisation useful for audiences

At ISOJ, Alberto Cairo, lecturer in visual journalism, University of Miami, raised some critical questions about the visualisation of data in journalism.

Cairo explained that an information graphic is a tool for presenting information and for exploring information.

In the past, info graphics were about editing data down and summarising it. But this worries me, he says, as it is just presenting information but does not allow readers to explore the data.

Today we have the opposite trend and often ends up as data art which doesn’t help readers understand the data.

Cairo cited a New York Times project mapping neighbourhoods which he said forced readers to become their own reporters and editors to understand the data.

We have to create layers, he said. We have the presentation layer and we have the exploration layer, and these are complementary.

But readers need help to navigate the data, he said. Part of the task is giving clues to readers to understand the complexity of data.

Cairo quoted a visualistion mantra by Ben Shneiderman: “Overview first, zoom and filter, then details-on-demand.”

His approached echoed earlier comments by Brian Boyer, news applications editor, Chicago Tribune Media Group. Boyer said that we should make data beautiful, inspirational but make it useful to the audience.
