Map Visualizer allows users to import csv files, and to create a map out of them using the plugin’s interface. 
After you have successfully imported (or created) a data source, you can visualise it on a map and add it to your posts/pages with a shortcode. 
All shortcodes can be constructed easily through the plugin’s interface.
<h4>CSV File Format</h4>
In order for the CSV file to be imported successfully, its format must comply with the following rules:
<ul>
<li>
The first row must contain all the Header names:
<ul>
<li>If you use geographical coordinates, the headers of the first two column must be named “Latitude” and “Longitude” respectively. </li>
<li>If you use addresses, the first column must be named “Address” and the plugin will geocode the data accordingly.</li>
<li>If you wish to use polygons, the first column must be named “Polygon”. Format of polygon data should be of Well-Known Text.</li>
</ul>
</li>
<li>
The second row must contain the data type of each column:
<ul>
<li>Available data types include “INT”, “FLOAT” and “TEXT”.</li>
<li>For “Latitude” and “Longitude” headers, the data type to be used is “FLOAT”.</li>
<li>For “Polygon” or “Address” headers, the data type to be used is “TEXT”.</li>
</ul>
</li>
</ul>
<h4>shortcode format</h4>
The general format of this plugin’s shortcodes is [visualise]. Available attributes include:
<ul>
<li>“file_name” : The name of the file imported you wish to visualise.</li>
<li>“map” : The map type to be used for the visualization. You can choose between “Satellite” or “Streets” maps and the default one is “Streets”.</li>
<li>“type” : Type of visualization. Either visualise your data as “polygon” or as “marker”. Default type is “marker”.</li>
<li>“marker_type” : Choose between “simple marker” or “circle_marker” to be pinned on the chosen map. The default markers are “simple marker”.</li>
<li>“category” : Header Name of your file, which will be used to differentiate the data based on the marker_type chosen.</li>
<li>“colorant” : Color of circle_markers and polygons, used to differentiate the data.</li>
<li>“circle_radius” : Radius of circle_markers. The default value is 5, and it is advised to stay between a 1-10 scale.</li>
<li>“fill_opacity” : Level of opacity for circle_markers and polygons. The default value is 0.3, and it is advised to stay between a 0.1-1 scale.</li>
<li>“center_point” : An Address for setting the initial center point of the map.</li>
<li>“zoom” : Initial zoom of the map. Value 1 shows the entire world map and the default zoom used is 3.</li>
</ul>

This plugin is extremely simple, and intended for someone who wants to add geocoding to their blog, but without the bloat of a big fat plugin. This lets you tag each post with a location (description, latitude, longitude) which can then be used in your custom theme.
This plugin also provides a feature to track of a single location not associated with any posts. This is useful in order to create a “Where Am I?” feature on your blog where you control the level of detail (just to share the city, rather than pluggin in foursquare data). This is especially nice if you’re running a travel blog or a website for some kind of tour.

EasyGeo

Adds simplest geocoding features to WP posts (description, lat, long). Adds nothing to the front-end, but has tools for you to do so in your themes.
