OECD Data Portal (economy, education, health, environment) publishes 1,545 open datasets for Global. Browse them live in Vizzie and turn any one into a map or chart.
OECD Data Portal (economy, education, health, environment) is the open-data portal for Global. It runs on OECD SDMX, an open-data platform. You can browse it directly at sdmx.oecd.org/public.
Licences here are declared per dataset via Portal-wide OECD Terms. 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.
OECD Data Portal (economy, education, health, environment) doesn't expose a machine-readable breakdown of who publishes what, so there's no reliable publisher ranking to show here. Vizzie still surfaces each dataset's own publisher as you browse.
