With Google My Maps, you can customize Google Maps for your own unique personal uses. You can create a map, (on which you can then draw lines, shapes, or placemarks), import a CSV, TSV, KML, KMZ, GPX, or XLSX file with geographically-specific data, organize your map with layers to hide or show different kinds of content, and style your content with different colors, placemark icons, and line widths.
