Graphical Modeler, that chain of processes (ie. GRASS modules)
can be wrapped into one process (ie. model). So it's easier to execute
the model later with slightly different inputs or parameters.
+<br>
+Models represent a programming technique used in GRASS GIS to
+concatenate models together to accomplish a task. It is advantageous
+when user see boxes and ovals that are connected by lines and
+represent some tasks rather than seeing lines of coded text. Graphical
+Modeler can be used as custom tool that automates a process. Created
+model can simplify or shorten a task can be run many times and it can
+also be shared with others. Important note is that models cannot
+perform specified tasks that one cannot perform manually with GRASS
+GIS. It is recommended to first do process manually, note the steps
+(eg. using Copy button in module dialogs) and later duplicate them in
+model.

+<h3>Components of models</h3>
+
+The workflow is usually established from four types of diagrams. Input and derived
+model data are usually represented with oval diagram.
+This type of model elements stores path to
+specific data on user's disk. It is possible to insert vector data, raster data,
+database tables, etc. Type of data is clear distinguishable in model by color.
+Different model elements are shown on the figures below.

+<h2>EXAMPLE</h2>
+
+In this example <tt>zipcodes_wake</tt> vector data
+and <tt>elev_state_500m</tt> raster data from the North Carolina
+sample dataset (original <a href="http://grass.osgeo.org/sampledata/north_carolina/nc_rast_geotiff.zip">raster</a> and
+<a href="http://grass.osgeo.org/sampledata/north_carolina/nc_shape.zip">vector</a>
+data) are used to calculate average elevation for every
+zone. Important part of the process is Graphical Modeler, namely it's
+possibilities of process automation.
+
+<p>
+In command console it would be as follows:
+
+<div class="code"><pre>
+# input data import
+r.import input=elev_state_500m.tif output=elevation
+v.import input=zipcodes_wake.shp output=zipcodes_wake
+# computation region settings
+g.region vector=zipcodes_wake
+# raster statistics (average values), upload to vector map table calculation
+v.rast.stats -c map=zipcodes_wake raster=elevation column_prefix=rst method=average
+# univariate statistics on selected table column for zipcode map calculation
+v.db.univar map=zipcodes_wake column=rst_average
+# conversation from vector to raster layer (due to result presentation)
+v.to.rast input=zipcodes_wake output=zipcodes_avg use=attr attribute_column=rst_average
+# display settings
+r.colors -e map=zipcodes_avg color=bgyr
+d.mon start=wx0 bgcolor=white
+d.barscale style=arrow_ends color=black bgcolor=white fontsize=10
+d.rast map=zipcodes_avg bgcolor=white
+d.vect map=zipcodes_wake type=boundary color=black
+d.northarrow style=1a at=85.0,15.0 color=black fill_color=black width=0 fontsize=10
+d.legend raster=zipcodes_avg lines=50 thin=5 labelnum=5 color=black fontsize=10
+</pre></div>
+
+To start performing above steps as automatic process with Graphical Modeler press
+<img src="icons/modeler-main.png" alt="icon"> icon or
+type <em>g.gui.gmodeler</em>. The simplest way of inserting elements
+is by adding complete GRASS command to Command field in GRASS command
+dialog (see figure below). With full text search one can faster
+module hunting. Then label and command can be added. In case that only
+module name is inserted, after <i>Enter</i> button pressing, module
+dialog window is displayed and it is possible to set all of usual
+module options (parameters and flags).

+<i>Figure: Dialog for adding GRASS commands to model.</i>
+</center>
+
+<p>
+All of used modules can be parameterized in model. That causes launching
+dialog with input options for model after model is run. In this example
+input layers (<tt>zipcodes_wake</tt> vector data and <tt>elev_state_500m</tt>
+raster data) are parameterized. Parameterized elements have a little thicker boarder
+in model scheme with diagrams.

+Final model, list of all model items, Python code window with <i>Save</i> and
+<i>Run</i> option are on figures below.

+<img src="g_gui_gmodeler_zc_items.png">
+<br>
+<i>Figure: Items with Python editor window.</i>
+</center>
+
+<p>
+After model is run with <img src="icons/execute.png" alt="run"> button
+and inputs are set, results can be displayed as follows:

+<i>Figure: Average elevation for zipcodes using North Carolina sample dataset as

+
+<p>
+Very useful advantage is that for example, this model can later be
+used to calculate (let's say) average precipe value for every
+administrative region in Slovakia using <tt>precip</tt> raster data
+from
+<a href="https://grass.osgeo.org/uploads/grass/sampledata/slovakia3d_grass7.tar.gz">
+Slovakia precipitation dataset</a> and administration boudaries of Slovakia from
+<a href="https://www.geoportal.sk/sk/zbgis_smd/na-stiahnutie/">Slovak Geoportal</a>
