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
Mathematica 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:
| Out[1]= |  |
Use
ProteinData to view a 3D molecule plot of a protein:
| Out[2]= |  |
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:
| Out[3]= |  |
Determine how many entities there are:
| Out[4]= |  |
Display the first 40 entities:
| Out[5]= |  |
Use
to see the available entity classes in
AstronomicalData. You can see that classes are types of objects:
| Out[6]= |  |
One of the classes is
. Show the list of planets in our solar system:
| Out[7]= |  |
Use
to see the specific data types associated with any class or entity:
| Out[8]= |  |
| Out[9]= |  |
Mass is one of these data types. View the mass of Saturn:
| Out[10]= |  |
Discover the satellites of Saturn:
| Out[11]= |  |
Determine the number of entities in
GraphData:
| Out[12]= |  |
Display the classes in
GraphData:
| Out[13]= |  |
Display the 705
entity in
GraphData:
| Out[14]= |  |
Show an image of a graph in
GraphData. In this case, the image is shown by default, without having to specify
:
| Out[15]= |  |
Explore the properties of
:
Display the first 25 properties of the above graph:
| Out[17]= |  |
Show the chromatic number of
:
| Out[18]= |  |
Show the classes that
belongs to:
| Out[19]= |  |
Explore the properties of the stevedore knot in
KnotData:
| Out[20]= |  |
Show the image of this knot:
| Out[21]= |  |
Show the braid diagram of the knot:
| Out[22]= |  |
Use
ChemicalData to see the properties of a chemical:
| Out[23]= |  |
Show the other standard names of the chemical:
| Out[24]= |  |
See the molecular plot of
:
| Out[25]= |  |
Display its structure diagram:
| Out[26]= |  |
Use
CountryData to see the first 25 data types associated with a country:
| Out[28]= |  |
View the agricultural products of the United States:
| Out[29]= |  |
Use
FinancialData to access information about stocks and other financial entities.
Calculate the ratio of the United States dollar to the euro:
| Out[30]= |  |
Find the latest price for General Electric stock:
| Out[31]= |  |
Plot the trading volume for General Electric for the first 11 months of 2003:
| Out[32]= |  |
Curated data integrates well with other
Mathematica functions.
Access different properties for chemical elements simultaneously:
| Out[33]= |  |
Put this data in a table and add row and column headers by prepending them to the list:
| Out[34]= |  |
