Data Report Generator

Problem addressed

When analysts already have a small set of structured metrics but still need a deliverable HTML report, manually assembling charts, narrative conclusions, and layout can consume disproportionate time.

How it works

The Data Report Generator accepts report_title, analyze_data, analyze_target, report_style, and author, then renders dictionary-like metric data into a single-page HTML report. The main steps are:
- Automatic chart selection: choose a pie, line, or bar chart based on the data shape and render it with Chart.js.
- Generated narrative: derive core conclusions, data insights, and optimization suggestions from maximum, minimum, and total values.
- Style templates: apply built-in “business formal”, “clean”, or “visualization-focused” templates that affect color, card style, and heading style.
- Export a viewable file: produce data_report.html by default, including the chart, analysis paragraphs, and raw data details.

Boundaries and caveats

This capability is best suited to scenarios where metric names and values are already clear, such as quarterly sales review, user growth analysis, or business efficiency evaluation. It does not perform data cleaning, missing-value handling, or complex statistical modeling. If analyze_data contains two-dimensional, nested, or mixed-unit data, flatten it into a simple metric dictionary first. The generated output is template-driven, so deep causal reasoning, business interpretation, and strategic judgment still require analyst input.
