Google Public Data Explorer
The Google Public Data Explorer allows users to upload their own datasets for visualization and exploration. To get started: Describe your dataset using the Dataset Publishing Language (DSPL), an open, XML-based metadata format optimized for data visualization. See the documentation on Google Code for more information. Bundle your data and metadata into a single Zip file, and upload it using the button below. Preview, share, and publish your dataset for others to see and use.
