Find the smallest number of colors that can be used to color the map. So that any to state sharing a stretch of common border or not colored with the same color. 
This image contains a simple line graph drawn on lined paper. Here is the transcription and explanation of the graph:

---

**Graph Explanation:**

This line graph represents a series of data points annotated with two-letter state abbreviations commonly used in the United States. The graph has three peaks, each labeled with the state abbreviations CA (California), UT (Utah), and KS (Kansas). There are also two troughs labeled as NU and CO (Colorado).

- **CA to NU:** The graph starts at a higher point labeled CA and drops to a lower point labeled NU.
- **NU to UT:** From NU, the graph rises to a peak labeled UT.
- **UT to CO:** The graph then falls from UT to a trough labeled CO.
- **CO to KS:** Finally, the graph rises again to a peak labeled KS.

This type of graph could be used to represent various kinds of data such as elevation changes between different locations or variations in a particular measurement (e.g., temperature, population) across different states over time. 

Please note that additional context would be necessary to fully understand and interpret the meaning of each point on the graph.
