1.11. Standard packages for 2D and 3D graphics  

     The standard add-ons Mathematica packages define some collection of additional functions for algebra, calculus, graphics, discrete and numerical mathematics, number theory, and statistics. Here some basic packages for 2D graphics are given.   

Standard graphical add-ons packages and its  functions Description   
 
<<Graphics`Graphics`    Loads the add-on package for graphics which allow the use of special functions  
       BarChart[ list]Depicts the data with a bar chart  
       PieChart[ list]   Depicts the data with a pie chart  
       PolarPlot[ ft, {t, tmin,tmax}  ]Draws a parametric polar curve ft, t is a parameter varying from  tmin to tmax.     
 
<<Graphics`Animation`Loads the add-on package for graphics animation  
      Animate [ gr, {t, tmin,tmax}   ] Animates the graphics  gr  with respect to the parameter  t.
      ShowAnimation[{gr1, gr2,...}]        Simultaneously animates the sequence of graphics objects stored in variables  gr1, gr2,...
 
<<Graphics`InequalityGraphics`   Loads the package which provides functions for visualizing logical combinations of inequalities over the reals in 2D, 3D and regions over the complexes.  
     InequalityPlot[ ineqs, {x, xmin, xmax}, {y, ymin, ymax} ] Draws the graphical solution of the set of inequalities ineqs in 2D
     InequalityPlot3D[ ineqs, {x, xmin, xmax}, {y, ymin, ymax}, {z, zmin, zmax} ] Draws the graphical solution of the set of inequalities ineqs in 3D space
