How to | Use Curated Data
An efficient load-on-demand mechanism makes hundreds of gigabytes of carefully curated and continually updated data immediately available inside the Wolfram Language for use in computations. This data, curated at Wolfram Research, can be accessed and processed in a coherent way.
Use AstronomicalData to load an image of the Earth:
Use ProteinData to view a 3D molecule plot of a protein:
Get a list of all the individual objects (or "entities") in AstronomicalData. Since this list is very long, only a very short sample of its beginning and end is returned:
Use "Classes" to see the available entity classes in AstronomicalData. You can see that classes are types of objects:
Determine the number of entities in GraphData:
Display the classes in GraphData:
Display the 705 entity in GraphData:
Show an image of a graph in GraphData. In this case, the image is shown by default, without having to specify "Image":
Explore the properties of the stevedore knot in KnotData:
Use ChemicalData to see the properties of a chemical:
Use CountryData to see the first 25 data types associated with a country:
Use FinancialData to access information about stocks and other financial entities.
