Treemaps are visualizations. In this video, learn how to create a treemap.
- [Instructor] The treemap, which is a relatively new type of visualization displays values as they contribute to a whole. So like a pie chart, a treemap uses the size of an area devoted to an input to indicate this contribution. Unlike a pie chart though, a treemap also uses shades of color to indicate values. Darker colors generally mean larger values while lighter shades mean smaller and you can even indicate negative values using specific colors such as black or white. In this movie I will show you how to create a treemap based on your business data. My sample file is 0908 treemap and you can find it in the chapter nine folder of your exercise files collection. I have a blank visualization option on my worksheet, so let's add some values to it. Let's say that I want to organize by product category, so I'll drag product category to the rows area and we'll go with order total as my measure, so I'll drag order total to the data area, I can see that there. If I want to visualize it using a treemap after I've created this text table, I can go over to the Show Me button and click it and then on the fourth row down the first item is the treemap button so I'll click that. Click Show Me to hide the panel and now we can take a look at our summary. As I described earlier, we have a visualization that breaks down contribution by order total by category. So robots provide the most revenue you can see that value there just under 2.5 million, drones 1.837 million, robot kits just over one million and so on. Treemaps are straightforward visualizations. I personally find them to be much more useful than a pie chart. Breaking down the value based on the area it takes up within the entire visualization as well as using color and shading to indicate a relative value makes the values at least in a relative sense much easier to understand. And if you want to see a specific value, just hover your mouse pointer over a section and the tool tip will indicate both the category and the total.
