✨ What this demo shows

This is a showcase for the mUI framework — specifically its Chart.js-inspired native chart widgets. The Cap Table app was built as a real-world stress test for the charting system and ended up being a fully functional tool.

• Native chart widgets — Pie, Doughnut, Line (with area fill + bezier tension), and Stacked Bar charts, all rendered natively in C++ with a Chart.js-inspired API
• Live recalculation — equity, dilution, and valuation update in real time as you edit any field
• Full dilution model — founder ownership tracked across multiple funding rounds with per-round investor series
• Color pickers per founder — charts update live as colors change
• JSON import / export — save and reload your cap table state
• Double-click inline editing — round titles and company name editable directly in the UI
• Tab state restoration — switching tabs preserves all live state

📐 Chart API

Charts are driven by a clean data-first API inspired by Chart.js:

auto chart = m_orch->getChart("valuationChart");

chart->configureStyle([](ChartStyle& s) 
{
    s.showTooltip = true;
    s.beginAtZero = true;
    s.fill        = true;
    s.tension     = 0.4f;
});

ChartData data;
ChartSeries s;
s.label  = "Post-Money";
s.values = { 0.f, 5'000'000.f, 25'000'000.f };
data.series.push_back(s);

chart->setData(data);

No browser. No JavaScript. Pure C++.
