The King of Treemaps - Smart Money’s Map of the Market - offers a classic set of measures: size represents market cap color represents change in market cap. Therefore, you can’t use ratios or dates or any other measure you wouldn’t use in a pie chart.Ĭolor of the boxes is best suited to a measure of performance or change such as growth over time, average conversion rate, or customer satisfaction. The sum of all the elements in one branch need to sum to the value of the branch as a whole. Also, we will learn to create Treemap in Qlik Sense. The measures should sum up along the hierarchical structure of the data. Moreover, we will look at the use of Treemap Qlik Sense Visualization. Size of the boxes should be a quantity measure. Choose the right measures for size and colorĮach box in a treemap can show two measures: I want to share some examples of the good and the bad in treemap design, and hopefully gather some feedback so we can continue to evolve our thinking.ġ. I won’t claim we have “cracked the code,” but we have gotten a feel for what works and what doesn’t. Over the course of these projects, we’ve thought a lot about the best way to make treemaps easy to understand and use.

Over the last year or so we’ve been building treemaps for our clients using our (recently open-sourced) Flex-based JuiceKit™ SDK. In contrast to basic charts where Stephen Few, Edward Tufte, and the Chart Chooser have laid down the law, treemaps roam the Wild West of interface design, obeying few rules, breaking many, and contributing to much infovis lawlessness.

However, treemaps aren’t easy to get right. The treemap chart graphs data as rectangles and the color represents the category, the rectangles allows you to compare the values since the proportions are relative to each other and the whole. Treemaps simultaneously show the big picture, comparisons of related items, and allow easy navigation to the details. The treemap chart is best for categories with few hierarchy levels, use the sunburst chart if you have many hierarchy levels. In the information visualization world, treemaps are on the rise…and justifiably so.
