An essential aspect of designing effective visual narratives is ordering. This is crucial for guiding your audience through your visualization and ensuring that they understand the story you’re trying to convey.
There are three primary methods of arranging the path viewers take through your visualization: linear, random access, and user-directed.
- Linear ordering: In this type of ordering, the viewer follows a prescribed path laid out by the designer. An example of linear ordering is a simple bar chart showing a company’s sales over time. The audience will naturally read the chart from left to right, following the time axis, and understand how the company’s sales have progressed. Linear ordering is effective when you have a clear story to tell and want to lead your audience through a specific narrative.
- Random access ordering: In this case, there is no prescribed path, and the viewer can explore the visualization freely. An example of random access ordering is a scatter plot showing the relationship between income and life satisfaction. The viewer can examine different points on the plot, identify outliers or interesting data points or patterns, and draw their own conclusions. Random access ordering is useful when you want to encourage exploration and discovery within the data.
- User-directed ordering: Here, the viewer must choose their own path among multiple alternatives. An example of user-directed ordering is an interactive map displaying crime rates in different neighborhoods of a city. The viewer can click on different areas to explore the data and make comparisons, deciding which aspects of the information they find most relevant. User-directed ordering is great for empowering viewers to interact with the data and customize their experience.
Remember, the key to successful data visualization is to guide your audience through the story you’re trying to convey in a clear, engaging, and informative way. By considering these tips and selecting the appropriate visual narrative ordering, you can create a powerful and effective data story that resonates with your viewers.
