add height and width to the map_canvas div and then check...

<div id="map_canvas" style="width:500px;height:380px;"></div>

You are missing the Google API key in the query parameter. Your script tag should be something like this:

src="http://maps.googleapis./maps/api/js?key=AIzaSyBeEeKz4H-KQTFABe1UTs9h5KUlpqsZ10Q&sensor=false"

You can register for a free Google map API key, which gives about 10,000 free hits everyday, good enough for practice purposes.
