Problem

The Analytics page shows aggregate statistics but no time-series visualisation. Users cannot see how a company's patent activity has evolved.

Work

  • Add a line or bar chart showing patent filing frequency over time (by year or quarter) to the Analytics page.
  • Add a stacked bar or pie chart showing technology category distribution over time.
  • Use an existing charting library (e.g., Recharts, which is common with React/Tailwind stacks) or add one.
  • Source data from the existing analysis results stored in PostgreSQL.

Acceptance Criteria

  • The Analytics page displays a filing-frequency trend chart for the selected company.
  • The Analytics page displays a technology-category distribution chart.
  • Charts are responsive and match the existing UI style.
