# Data taken from Wikipedia

# 3 stars closest to Earth

lightyears = [4.2, 4.3, 5.9]

temp = [2883, 5753, 3134]

# Scatterplot example

# Subplot creates a figure similar to a painting canvas

fig, ax = plt.subplots()

# Used Claude.ai to assist with next line

# Creates a scatterplot, with the line purple

# Data points marked with "*"

# The "s" parameter makes the star bigger

# The default size is quite small; maybe 20

ax.scatter(lightyears, temp, color='purple', marker="*", s=600)

# Sets title

ax.set_title("Distance/Temp of Stars Closest to Earth")

# Sets x axis name

ax.set_xlabel("Star Distance")

# Sets y axis name

ax.set_ylabel("Star Temperature")

# generate a full grid

plt.grid()

# show plot on screen

plt.show()
