Sentence Stats is a Go tool for visualizing character and character pair frequencies in sentences. It generates histogram plots to help analyze the composition of text.

• Character Frequency: Visualizes the frequency of each character in the input text.
• Character Pair Frequency: Visualizes the frequency of character pairs (bigrams), ignoring order (e.g., "ab" and "ba" are counted together).
• Sentence-based Analysis: Processes input sentence by sentence (split by '.').
