Codeforces Rating-Based Heatmap

This Chrome extension enhances Codeforces user profiles by adding a rating-based heatmap that visually represents problem-solving activity. Unlike the default heatmap, which only counts the number of problems solved per day, this extension highlights each day based on the difficulty of the hardest problem solved. KEY FEATURES: 🔹Accurate Rating Heatmap: The heatmap color on a given day represents the maximum rating of a problem solved that day. 🔹Quick Insights: Hovering over any day in the heatmap shows a tooltip displaying detailed information about the problems solved on that day. The tooltip includes: • Problem Name • Problem Rating • Direct Link to the Problem • Indicator if the problem is a duplicate 🔹 Multi-Year Support: Users can analyze their performance across multiple years, allowing for a comprehensive view of their progress over time.
