I have a raw dataset that I need turned into clear, insightful line-chart visualizations so I can quickly spot trends and patterns over time. Here’s what I’m after: • Clean and prep the data (I’ll share it as a CSV). • Design one or more line charts that make the key movements instantly obvious. If a small supporting element—such as a tooltip, shaded range, or secondary axis—helps highlight a story, feel free to include it. • Build the visuals in a mainstream tool you’re comfortable with: Python (Matplotlib, Seaborn, Plotly), Tableau, Power BI, or D3.js are all fine as long as I receive the editable file and a brief “how-to-update” note. • Deliver high-resolution image exports plus the working file/code so I can reuse the chart in reports and presentations. Accuracy, readability, and a streamlined hand-off matter more to me than flashy extras. If you have examples of past trend-focused line charts, please link them when you respond.
