sales-report

A sales review is one Markdown file with exactly these sections, in this order. ```markdown # <Quarter> Sales Review ## Headline - **Total revenue**: CNY <total, thousands-separated, 2 decimals> - **Total units**: <integer> - **Top region**: <region> (CNY <revenue>) ## By region | Region | Revenue (CNY) | Units | Share | | --- | ---: | ---: | ---: | | ... | ... | ... | ... | Sorted by revenue, highest first. Share is a percentage of total revenue with one decimal. The last row is a **Total** row. ## Trend  One sentence naming the strongest and weakest month. Unless the request says otherwise, the chart is revenue by month. ## Data notes - One bullet per data-quality problem you had to correct, naming the affected column, how many rows it hit, and what you did about it. - `- none` if there were none. ``` ## Chart rules No plotting library is available, so write the SVG by hand: - at most 640×320, with `viewBox`, and no external fonts, images or CSS; - one axis line, every bar or point labelled with its value; - a single accent colour plus a grey axis — no gradients; - round numbers on the axis, not raw maxima. ## Rules - Every figure in the report comes from the extract. Never carry a number over from a previous draft — recompute it. - Money is CNY, two decimals, thousands-separated. Units are integers. - Keep the whole report under 60 lines.
