dados.gov.pt publishes 20,896 open datasets for Portugal. Browse them live in Vizzie and turn any one into a map or chart.
dados.gov.pt is the open-data portal for Portugal. It runs on uData (data.gouv.fr family), an open-data platform. You can browse it directly at dados.gov.pt.
Licences here are declared per dataset via Per-dataset `license` field. A machine-readable summary of the licence mix isn't available yet, but Vizzie surfaces each dataset's declared licence (or notes when none is given) as you browse — remember that an undeclared licence is not the same as public-domain or free-to-use, so check before you reuse.
