Yearly Sales Trend Analysis

I have a complete set of yearly sales figures that I need explored in depth. My main objective is to surface clear trends hidden in the numbers—patterns in revenue growth or decline, seasonal shifts, product or regional out-performance, and any anomalies that merit a second look.

All raw data are already cleaned and stored in spreadsheets; if you prefer working in Python (Pandas, NumPy, Matplotlib/Seaborn) or an R environment, that’s fine—just let me know your choice so I can grant access to the files in the right format. Please feel free to bring your own BI tool for supplementary dashboards if it speeds up iteration.

Deliverables I expect
• A concise written report outlining the key trends you discover, backed by summary statistics.
• Clear visualizations (charts or dashboards) that illustrate those findings so I can present them internally without additional tweaking.
• A brief explanation of the methodology you used—enough that another analyst could reproduce the results.

Accuracy and clarity are more important to me than flashy design; every chart should directly support the narrative in the report. If anything in the dataset looks inconsistent, flag it and we can discuss before proceeding.
