I do this in two possible ways, dependent on the type of data.
When choosing your layer properties you choose for 'graduated' or 'categorized', then you have a 'Advanced' button below, at the right side. There you can choose a parameter to be the size of the symbol. Pay attention that the value of the parameter will be the font size (so if you are working ...

<!-- Mapping curve definition pairs (input, output) -->
<ogc:Literal>70</ogc:Literal> <!--smallest input value -->
<ogc:Literal>5</ogc:Literal> <!-- smallest point size -->
<ogc:Literal>72</ogc:Literal> <!--largest input value -->

You should be able to run a Frequency on the feature. Just select your "Constituen" field for the frequency field in the input and then join the output on the same field.
Although it is an extra step to the summary statistics, it will definitely work on a text field, and should work on any field type you throw at it.

It is. My opinion that these are flood control structures. Berms if-you-will?
Here they are used as impervious (paved) runoff holding ponds along and near water tracks.
Probably considered man made berm or control structure.

Really not a definitive answer but an answer to complete more (waiting community :) !
The main ideas why SLD is not used everywhere as a data exchange is history, verbosity, extensibility, output support.
History
ArcGIS comes before the SLD standard exists.
MapInfo format doesn't separate style from content so you can't separate data from rendering like ...

To do this I would use the Summary Statistics tool which has a COUNT option.

The simplest (but most manual) solution to this is an Excel PivotTable. Load your attribute table into Excel. Select all of your data. Choose Insert > PivotTable. Throw Pointlabel or PointValue into the ROW LABEL and VALUES box, and make sure that COUNT is selected on VALUES (sometimes it will default to SUM, which is not what you want).
A form may be ...

I just tested this and it worked!
The layer file that I added, and then changed the data source of, was saved from a layer called dummy that pointed at a dummy.shp file.
import arcpy
mxd = arcpy.mapping.MapDocument("C:\\MAPS\\map.mxd")
df = arcpy.mapping.ListDataFrames(mxd,"Layers")[0]
addLayer = arcpy.mapping.Layer("C:\\SYMBOLOGY\\symbology.lyr")

I haven't tested this out, but the easiest way should be to simply rename (or copy) symbology.lyr to points.lyr (the same basename as your shapefile). Generally speaking, when you load a shapefile into ArcMap that has a similarly name Layer file, the symbology of the layer "follows" the raw data (shapefile) and is applied on load.

Your symbology rendering, scaling, and labeling is defined within your map document. To define layer scales:
Right click each layer in the Table of Contents and select Properties
Select the General tab and define min and max scale for each layer
Save your map document, and then re-publish your service

I'm not sure if this answers your question but here's how you do it in QGIS
What you need:
Bird point vector layer
In that layer, you should have a unique field (row) that identifies those birds species categories
Process:
Right click the layer, then click on Properties
Click on the Style on the left
In the Style (top of the window) drop down click on ...

We have done so using our RW Net 4 package for calculating flow from your CSV-data and then used line thickness for illustration of volume. In this example all flows are from a single location:

I haven't tried this personally, but it looks like you need to access the GraduatedColorsSymbology class on the layer. Have a look at the second example at the bottom of this page.
It also looks like you may need to have an existing lyr file with the graduated colours already set in order to use UpdateLayer.
