I'll take a look at the GitHub-style contribution chart and fix the issue. Let me analyze the problem and provide a solution.

With these updates, the GitHub-style contribution chart should now display correctly, with a layout that closely resembles the actual GitHub contribution graph. The chart will show 52 weeks of data, properly sized squares, and include day and month labels for better readability.

Is there anything else you'd like me to adjust or improve in the chart?
