If you want to display a range of data by region, you need a GeoMap. You may not have known this, but it's quite easy to create your own in Google Sheets after entering your data.
Highlight the data and go to Insert > Charts. On the charts tab of the new window you can select maps and choose which type of map you want. On the customize tab you can choose the colors and select which region you want. I created a map for the U.S., but you can choose to create a map for the world instead, or a select number of other regions.
