+# Conversas com Claude.ai - Componentization
+
+## Passo 1 - Módulo / Pacote
+
+Consider the following code:
+
+
+```
+import pandas as pd
+import matplotlib.pyplot as plt
+
+df = pd.read_csv('intake-person-demo(potato-chips).csv')
+
+plt.figure(figsize=(10, 6))
+scatter = plt.scatter(df['age'], df['intake_bw'], c=df['intake_bw'], cmap='viridis')
+
+plt.xlabel('age')
+plt.ylabel('intake_bw')
+plt.title('Age vs. Intake (body weight)')
+
+plt.colorbar(scatter, label='intake_bw')
+
+plt.show()
+```
+
+How can I reorganize this code in two functions (table and scatter_plot) and a main code that call them?
+* table: receives the path as parameter and reads the CSV, returning the data
+* scatter_plot: receives the data, xfield, yfield, and title, ploting the scatter plot
+xfield and yfield are both the name of the field in the CSV and its label.
