# Data Release Summary Statistics in Atlas

The Atlas **Data Sources** option allows you to create **FinnGen data release-level descriptive summary statistics.**

### **Example: Drug exposure** statistics

* Choose the **Data Sources** option from the left menu
* Select the FinnGen data release from the first drop-down menu (we have selected the FinnGen data release 9 below)
* Select **Drug Exposure** from the second drop-down menu

#### Treemap display

By default, the summary statistics are shown using a Treemap.

In our example:

* the boxes represent different drugs
* the box size shows the prevalence of the drug
* the box color shows the number of records per person (a darker color means more records)

Hovering the mouse above a box gives details about the drug it represents.

#### Table display

* To see the information in a table format click the **Table** tab

The table will show the drug names, ingredients, person counts, prevalence, and records per person:
