Introduction to Data Visualization
Data visualization is a powerful tool for makers and creators because it helps you see patterns, trends, and progress in your projects that might otherwise be hidden in raw numbers. Whether you are tracking how quickly you finish different stages of a build, monitoring sensor readings from a DIY device, or showcasing your creative process to others, visualizing data makes your results clearer and more engaging. For example, you might want to plot the completion percentage of each step in a project to better understand your workflow and identify any bottlenecks.
1234567import matplotlib.pyplot as plt # List of project completion percentages over time completion = [10, 25, 40, 60, 80, 100] plt.plot(completion) plt.show()
This code uses the matplotlib library to turn a simple list of numbers into a visual line chart. The list completion holds the percentage of a project completed at different checkpoints. The plt.plot(completion) function creates a line that connects these points, and plt.show() displays the chart in a separate window. By converting your data into a visual format, you can instantly grasp your project's progress and spot any irregularities or patterns that might need attention.
123456789import matplotlib.pyplot as plt completion = [10, 25, 40, 60, 80, 100] plt.plot(completion) plt.title("Project Completion Over Time") plt.xlabel("Checkpoint") plt.ylabel("Completion (%)") plt.show()

Can you explain what each part of the code does?
How can I customize the chart further?
What other types of data can I visualize with matplotlib?
Чудово!
