There are plenty of different chart types that businesses can use for data visualisation. A treemap chart is a graphical representation of data that uses rectangles, called nodes, to represent different hierarchical levels of data. The width and height of the nodes are proportional to the quantity of data at that level. The colour of the node indicates the data type. Treemap charts are particularly well-suited for representing nested data structures. It has a tree-like format with branches and sub-branches. This is what makes it visually appealing and easy to read.
What are some components of a treemap?
A treemap is composed of squares, rectangles, or circles that are sized and coloured to indicate the relative magnitude of the data values they represent. The larger the area of the shape, the greater the value. The colour of the shape also conveys information, with green indicating the lowest value, yellow indicating a higher value, and red indicating the highest value.
The treemap chart is effective in displaying data because it uses a colour scale to indicate magnitude, is easily scalable to large data sets, and shows hierarchical data in an easily understood way.
When should you use a treemap?
Treemaps are used to display hierarchical data. The data is displayed as a set of nested rectangles, where the size of the rectangle is proportional to the value of the data. This type of chart is often used to display the breakdown of a large dataset into its component parts.
What are the steps to create a treemap chart?
To create a treemap chart on your work computer, you will need to decide what data to chart. In general, treemap charts are used to visualise hierarchical data. This could be data that is organised by category, such as products in a store, profits in PPC advertising, or data that is organised by size, such as the sales revenue for different products.
Once you have decided what data to chart, you will need to come up with the three main sections: the plot area, chart title, and legend. The plot area is the visualization of the collected data. Each rectangle is coloured in shades of the highest level category. Make sure to give the chart a descriptive title so that it’s easy to understand. The legend helps readers differentiate one data set from another depending on the colour.
To create a treemap chart through a program, one can use Microsoft Excel or any other software. Create the categories and columns for your data. Enter all of the appropriate information in each column for each category. Make sure your data is categorised and in the proper order. Then, simply highlight the data and hit the “Insert” tab then choose the “Insert Hierarchy Chart” option. After that, you can choose the “Treemap” options.
You can double-click the chart to format it, edit the title, or change the colours. There are plenty of ways to customise the chart.
When is the best time to use a treemap chart?
Treemaps are a great way to visualise hierarchical data. They can be used to represent the contents of folders and files, as well as to show the relationships between data items. There are a few things to keep in mind when using treemaps.
First, the width of each branch should be proportional to the number of items it represents.
Second, the area of each square should be proportional to the value of the data item it represents. Third, the order of the items in the treemap should reflect the hierarchy of the data. Overall, the last category will have the smallest amount of data and have the smallest width.
Now that you know how to create a treemap and when to use it, you can start discerning patterns and making comparisons to improve your business.
