SIMPLE THEMATIC MAP USING ARCVIEW
Click on the + button "add theme"
Navigate to .shp files:
click on cntry94.shp, for example.
Note now that there is, to the left of the view area, a small bar with a little swatch of color in it. Click on the small button to the left of the color swatch to draw the map.
Next, double click on the layer.
Pull-down the "legend type" arrow: choose "graduated color."
Pull-down the "classification field"--choose "area"
Click on the "apply" button--note that you can see the changes in the map underneath and still have the window in which you were working be open. Now pull down "color ramps"--try a variety of different selections to see how these work.
Close the "legend editor" and see how your map looks. Try making a number of different maps.
