Executive Summary

Many product, analytics and editorial teams struggle to represent dated events that repeat or cluster around a year—building circular "seasonality" wheels requires non-trivial trigonometry, bespoke SVG work, timezone/date edge-case handling, and ends up fragmented across engineering and design teams. The result is slow product iterations, inconsistent UX, and high build/maintenance cost for a visualization many teams need only occasionally. You could ship a lightweight, framework-native component library (React/Vue/Svelte) that uses an API-driven trigonometry layer to deterministically place points, ranges and recurring events on annual wheels, with built-in interaction, accessibility, theming, export, and integrations for analytics. Deliver an open-source core for adoption and a commercial tier with enterprise features (SSO, support, licensing, PDF/print quality exports) to monetize. This is a timely opportunity: the market is roughly $1.2B (200,000 product/analytics teams × $6K ACV), and current trends—componentization, design-first data storytelling, and dual OSS/commercial models—favor a niche, embeddable visualization product (market score 85/100, revenue potential 80/100). You can differentiate by offering framework-native polish, a predictable API for the math (reducing engineering overhead), robust timezone/date logic, and strong docs/templates; but expect medium competition from generic chart libraries, and plan for the ongoing support burden and need for enterprise sales.

Market Opportunity

Place dated events on circular (annual) wheels with API-driven trigonometry targets a $1.2B = 200,000 product/analytics teams × $6K ACV for visualization components and licenses total addressable market with medium saturation and a year-over-year growth rate of 12% YoY growth — inferred from frontend tooling demand, component marketplaces, and data visualization market reports (combined signals from Stack Overflow trends and industry reports).

Key trends driving demand: Componentization — product teams prefer ready-to-use, framework-native components which reduces build time and increases demand for specialized UI libraries.; Design-first data storytelling — product and editorial teams increasingly use bespoke visualizations (timelines, seasonality rings) to tell data stories, creating demand for niche components.; Open-source + commercial licensing — developers expect free OSS for prototyping but enterprises demand commercial licenses and support for production use, enabling dual-license business models..

Key competitors include D3.js, Highcharts, amCharts.
