📌 Python Bar Chart Example — Code Breakdown

x = ['A', 'B', 'C']
y = [1, 10, 3]

plt.bar(x, y)
plt.show()

✅ Step-by-Step Explanation

1️⃣ x = ['A', 'B', 'C']
This line creates a Python list called x.
It contains three category labels: 'A', 'B', and 'C'.
These will appear on the X-axis as labels for each bar.

2️⃣ y = [1, 10, 3]
This line creates another list called y.
It contains the numerical values that determine the height of each bar:

A → height 1
B → height 10
C → height 3

3️⃣ plt.bar(x, y)
plt refers to matplotlib.pyplot — a powerful Python plotting library.
plt.bar() is the function that draws a vertical bar chart:

The first argument x is the list of categories (bar labels).
The second argument y is the list of values (bar heights).

So:

The first bar is labeled A and is 1 unit tall.
The second bar is labeled B and is 10 units tall.
The third bar is labeled C and is 3 units tall.

4️⃣ plt.show()
This line displays the chart in a window (or inline if using a Jupyter Notebook).
Without plt.show(), the chart won’t appear.
🔍 What This Code Does

This simple code snippet plots a bar chart with three bars.
Each bar represents a category (A, B, C) with its corresponding height (1, 10, 3).
⚡️ What You Can Try Next

Add a title:
plt.title("My Bar Chart")
Label the axes:
plt.xlabel("Category")
plt.ylabel("Value")
Save the chart as an image:

plt.savefig("bar_chart.png")

✅ Matplotlib is great for creating visualizations in Python — perfect for data analysis, science projects, and more!
