You use uploaded data source files to create visualizations in projects.
Note:
You can also use the Data Sources page to upload data files. For more information see Managing Data Sources.Note:
If you upload a file to a project that has the same name as an existing uploaded data source, the system reminds you that the existing data source will be overwritten by the new one. If you don't want this to happen, be sure to give the new upload file a unique name.Note:
A column that is unavailable and marked with a red information symbol is invalid and will be excluded. Typically, this happens because the column name is a duplicate or it contains illegal characters (leading or trailing spaces, or special characters). You can hover over the symbol to see the reason why the column is invalid.
