35  Interactive HTML Modules

35.1 Purpose

Interactive modules help students see how mathematical finance models respond to parameter changes. The book loads Plotly.js once in _quarto.yml, so chapter pages can include lightweight HTML containers and JavaScript functions.

35.2 Suggested Interactive Modules

Module	Concept	Controls
1	compound growth	rate, horizon, compounding frequency
2	binomial tree	\(u\), \(d\), \(r\), number of steps
3	Brownian motion	path count, time horizon, volatility
4	GBM	drift, volatility, initial price
5	Black–Scholes call	strike, maturity, volatility, rate
6	Greeks	moneyness, volatility, time to maturity
7	Vasicek short rate	mean reversion, long-run mean, volatility
8	efficient frontier	covariance and target return
9	VaR and ES	confidence level and loss distribution
10	Heston simulation	variance mean reversion and vol-of-vol

35.3 Example Container

A chapter can add a container such as:

<div id="mf-compound-demo" class="plotly-demo"></div>

Then assets/math-finance-interactives.js can populate the figure when the page loads.
