Investor cash-flow chart + IRR per structure (solo / JV / syndication)

[georgymh]

Visualize the investor's cash flows for solo / JV / syndication scenarios. Standard $50k–$100k LP check size, plotted by year (Y0 negative, then per-year distributions, plus sale and refi proceeds).

Open questions

• Library choice: vanilla SVG, Recharts, or Chart.js? Lean toward minimal-dep (SVG) given the rest of the stack.
• IRR calc: Newton-Raphson on the cash-flow vector. Inline implementation; no external lib needed.
• Stacked bar coloring: distinguish operating CF, refi proceeds (Syndication fees & executive summary (acq / asset mgmt / disposition / refi) #10), and sale proceeds.
• Side-by-side: render solo / JV / syndication on the same chart, or three small charts?
• Investment size: single field at the top of the section ($50k default).
