# Populating a Scatter chart

1. Select the shape by `name` you want to modify. See [here](https://docs.powerpointgeneratorapi.com/knowledge-base/finding-shape-names) to find shape names.
2. Under `data`:
   1. Define the main dataset for the chart.
   2. Use `additional_data` to insert extra information into specific cells in the chart’s data table.
   3. Each `cell_target` defines where the data will start being written.
