How to chart gamma exposure (GEX)

How to chart a performance attribution waterfall
An attribution waterfall has one job: bridge the benchmark return to the portfolio return with bars that sum exactly. Most write-ups teach the Brinson algebra and skip the chart.
How do I embed an interactive chart in a LinkedIn newsletter?
You cannot. LinkedIn articles accept embeds only from an approved provider list and reject third-party code outright, so the working pattern is a static image plus a link.
How do I put a chart in an email that survives Outlook and Gmail?
Email clients strip iframes and JavaScript, so an interactive chart cannot be embedded in one. The working pattern is a frozen image plus a link, and finance charts get it wrong in specific ways.

A returns box plot groups monthly returns by calendar month and shows the spread, not the single value. Keep months in calendar order, draw the zero line, and count n.

How to chart a QQ plot of returns to test for normality
Sort your returns, plot them against normal theoretical quantiles with a 45-degree line, and read the tails: an S-shape means fat tails and a dip on the left means negative skew - the reason a normal-based VaR understates risk.

How to chart a rolling beta against the market
A single beta hides how market sensitivity drifts. Compute cov(asset, market) / var(market) over a rolling window, draw the beta = 1 line, and name the benchmark.

A rolling Sharpe shows when risk-adjusted return decayed, which a headline number hides. Annualise by the square root of time (not time), use a 252-day window, and draw the zero line.
How do I embed an interactive chart in Framer?
Embed a chart in Framer with the Embed element's HTML option and paste the iframe. The step most miss: size it explicitly and make it responsive, because an iframe will not resize itself.
How to build a correlation matrix heatmap for a portfolio
A correlation heatmap shows where your diversification actually is. Correlate returns not prices, use a diverging scale fixed to -1..+1, and remember the matrix is one moment in time.
