# Most basic treemap ***

This is the most basic [treemap](treemap.html) you can do. The input dataset is simple: we just have 3 groups, and each has a value which we map to an area. It allows to learn the syntax of the `treemap` library: you need to provide at least a dataset (`data`), the column that provides groups (`index`), and the column that gives the size of each group (`vSize`). See graph [#235](235-treemap-with-subgroups.html) to learn how to add subgroups, and graph [#236](236-custom-your-treemap.html) to customize the chart appearance.

```{r thecode, echo=FALSE, out.width = "100%", fig.height=7} # library library(treemap) # Create data group

```{r thecode, eval=FALSE} ```

```{r, echo=FALSE} htmltools::includeHTML("htmlChunkRelatedPartOfWhole.html") ```
