Last week I spoke at a joint data visualization Meetup group to more than 200 people from around the world. Randy Krum from CoolInfographics was kind enough to set up a joint Meetup event with 11–yes, 11!!–different Meetup groups from around the United States. For this event, I developed a new talk about creating a data visualization style guides, a topic I commit an entire chapter to in my recent book, Better Data Visualizations.

I focused on three main themes in the talk:

  • Why have a style guide?
  • What should your style guide include?
  • How do you develop your style guide?

I then tied these themes together to talk about the original design and current redesign of the Urban Institute data visualization style guide.

I’ve written about these issues in the past (see, for example, here, here, and here), but one question caught my ear during the Q&A section of the evening:

How should an organization get started developing a data visualization style guide?

This is such an important question. You might strongly believe a data visualization style guide would help you and your organization be more effective and consistent, but how do you get started?

Like many other issues that come with introducing better data visualization practices to an organization, I think the best way to success is demonstrating how to move forward. In this case, if you can create a simple style guide–basic colors, font, standard placement, and maybe even create a template in your data visualization tool–you can show your colleagues, managers, and others how a style guide can be beneficial.

Demonstration is everything

I don’t think you need to go all the way and include all eight sections in your style guide that I talked about in my talk, as I show in the slide below, but at least setting up the core elements of a style guide can help you demonstrate its value. You could even borrow the styles in an existing style guide just to demonstrate how it might look at your organization. While culture change can be hard, in this case, I think these kind of style guides can have immediate and obvious positive effects on consistency and productivity.
