Google Data Studio allows you to create dashboards from any number of data sources: Adwords, BigQuery, MySQL, Google Analytics, Youtube and Google Sheets.
I usually dump data from many different sources into a Google Sheet, then connect it to Data Studio to create charts.
Once you connect a data source, you'll be prompted to check that your columns are being pulled in correctly. There are two things to watch out for:
1) Are columns being properly picked up as metrics or dimensions? Metrics are fields that can be counted (ie are numbers), and dimensions are fields that you'd use to group data by (usually text fields).
2) Are date fields being recognized properly? This is important, as you'll need a date field to make any type of time series charts.
