The dataset list for data visualization in 2026 revisits earlier picks and refreshes them for continued relevance. Current entries include updated links and metadata, along with notes on major changes such as new APIs, deprecated sources, or license updates. New dataset suggestions are added as alternatives to provide more options when searching. Each entry provides a brief description, an official link, estimated size, license information, recent changes, and visualization ideas. The list includes U.S. government open data via Data.gov, which indexes hundreds of thousands of datasets and is generally public domain. It also includes World Bank open data, offering thousands of datasets and time series across countries under CC BY 4.0, supported by key APIs.
"Today. We're going to revisit ODSC's " 12 Must-Use Datasets for Data Visualization " list and refresh it for 2026. But before we dive in, we took the time to review all the original picks for continued relevance, and in doing so, we kept those still current, updated links and metadata, and noted any major changes (including new APIs, deprecated sources, or license updates). When it comes to a new dataset, suggestions are added as alternatives, giving you more choices when it's time to look for one."
