Your data needs to be studied w.r.t two quantitative values.Įach rectangle (node) in the treemap chart showcases the values for two quantitative values. Letâs take a look at what are the ideal use cases that warrant the use of a treemap chart: Like every chart type and data visualization technique, the treemap charts works well only if it is used in situations that justify its use. Read on to know the best situations in which you can use your treemap chart to utmost advantage. That said, charting facilitates the desired analysis only when data is visualized on the right type of chartâif youâve worked with data visualization extensively, youâd know that this varies not just basis your data, but also basis the kind of analysis you want to facilitate.
