The entire process is fairly simple.
Amazon QuickSight seamlessly discovers data in popular AWS data repositories. So, simply point Amazon QuickSight to one of the discovered data sources.
Then, select a table and start analyzing your data. You can also upload spreadsheets and CSV files and use Amazon QuickSight to analyze your files.
To create a visualization, start by selecting the data fields you want to analyze, or drag the fields directly on to the visual canvas, or a combination of both actions. Amazon QuickSight will automatically select the appropriate visualization to display based on the data you’ve selected.
