Dataset as an Annotation

Dataset objects can be used directly as an annotation of EntityValue.

Construct a dataset of properties of noble gases.

In[1]:=

gases = EntityValue[
  EntityClass["Element", "NobleGas"], {"BoilingPoint", "Density"}, 
  "Dataset"]

Out[1]=

Find the two atoms with the highest boiling point temperature.

In[2]:=

gases[TakeLargest[2], "BoilingPoint"]

Out[2]=

Find the two atoms with the smallest density.

In[3]:=

gases[TakeSmallest[2], "Density"]

Out[3]=

Visualize on a two-dimensional plot the density and boiling point of each noble gas.

In[4]:=

ListLogPlot[gases, Frame -> True, FrameLabel -> Automatic]

Out[4]=
