I'm curious about creating a map application that can input and display a 3km radius around a specific location. Any guidance would be greatly appreciated. Please excuse my imperfect English (haha).

If you're looking to geocode an address and create a circular boundary around it, there are specific steps you need to follow. First and foremost, you'll have to connect a Google Map to a particular element on your webpage - in this case, the sample code is linking it to a div with the id "map".
function geocodeAndMapLocation(address) {
var geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var mapOptions = {
zoom: 16,
center: results[0].geometry.location,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var locationMarker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
var plottingCircle = new google.maps.Circle({
map: map,
radius: 3000,
fillColor: '#660000'
});
plottingCircle.bindTo('center',locationMarker,'position');
}
});
}
