Planning plot for rankings

I’m thinking about how to set up a CSV that contains rows of round and team ranking positions. However, I really want to focus on plotting the ranking trends of the top 4 teams across matchweeks. Without data, I realize that I need to prepare code that expects a weekly table detailing the teams and their ranks. For that chart titled "前四排名走势图", it'll need to show the rank trajectory for those top 4 teams throughout the season. I'll outline the approach and write a script named plot_csl_top4.py that includes data from two CSV files.Summarizing ranking changes

I need to compute how many times rank 1 changed ownership, counting distinct transitions while ignoring consecutive repeats. I'll also determine the longest consecutive leader streak and create a leaderboard showing how many weeks each team led. I’ll produce a line plot that displays these changes and includes annotations for leader changes. However, without data, I can’t provide specific details, just a takeaway summary in Chinese highlighting the competition's intensity and possible team rotations. I’ll ask if the user wants a breakdown by rounds or teams.Offering data extraction options

I’ll say, "如果官方图显示, 我可以提取具体轮次和球队." I want to offer to extract data from an image if the user pastes the chart image since image input is enabled. I'll request them to upload the chart so we can read it and compute stats. Additionally, I'll propose an option to compute from text data. My response in Chinese will include concise options:

1. 要点速览和解读
2. 数据提取与统计
3. 生成可分享可视化
4. 若要写稿

I'll keep it within 4-6 bullets and consider offering the analytic script option with a code block.Providing concise options

I aim to keep my initial reply short and ask the user what they need. I want to offer to analyze the chart if they share it, generate a plot, and optionally provide a brief commentary. So, I’ll structure my response with bullet points:

• 关键词: 2025赛季 中超 前四 走势 榜首12次易主
• 简短解读: 说明竞争激烈; 排名稳定性低; 冲刺阶段可能集中易主.
• 你希望我做什么:
  1. 提要/通稿
  2. 梳理所有易主轮次与球队
  3. 从你给的图或数据做可视化与统计
  4. 生成社媒配文

Let’s get started!
