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:

Determine how many entities there are:

Display the first 40 entities:

Use "Classes" to see the available entity classes in AstronomicalData. You can see that classes are types of objects:

One of the classes is "Planet". Show the list of planets in our solar system:

Use "Properties" to see the specific data types associated with any class or entity:

Mass is one of these data types. View the mass of Saturn:

Discover the satellites of Saturn:

    

Determine the number of entities in GraphData:

Display the classes in GraphData:

Display the 705^(th) 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 TriangleReplacedCoxeterGraph:

Display the first 25 properties of the above graph:

Show the chromatic number of "TriangleReplacedCoxeterGraph":

Show the classes that "TriangleReplacedCoxeterGraph" belongs to:

    

Explore the properties of the stevedore knot in KnotData:

Show the image of this knot:

Show the braid diagram of the knot:

    

Use ChemicalData to see the properties of a chemical:

Show the other standard names of the chemical:

See the molecular plot of "4-MethoxyCinnamicAcid":

Display its structure diagram:

    

Use CountryData to see the first 25 data types associated with a country:

View the agricultural products of the United States:

    

Use FinancialData to access information about stocks and other financial entities.

Calculate the ratio of the United States dollar to the euro:

Find the latest price for General Electric stock:

Plot the trading volume for General Electric for the first 11 months of 2003:

    

Curated data integrates well with other Wolfram Language functions.

Access different properties for chemical elements simultaneously:

Put this data in a table and add row and column headers by prepending them to the list:
