The queries that Geo-visualization calls to create data visualizations reference the source data from structured datasets. Datasets are created by importing files of CSV-delimited values, interpreted as columns defining data parameters and rows representing the data entries. You upload data to your Geo-visualization account, and your datasets can be selected as the source for as many visualization queries as required.
You can upload data directly from a file or by specifying a URL. It is also possible to upload data from an SFTP server. See Managing your Data for more information. Note that datasets must follow certain formatting rules; see Data Format Guidelines.
