48-Month Table

The table is empty until you click the render button. If you switch scenarios after the table is already visible, the page automatically re-runs the selected scenario through the JavaScript engine and updates the displayed HTML table.

Table not loaded yet.

Framework Graph Demos

Each graph button lazy-loads its chart framework from a CDN, runs the selected scenario through the JavaScript engine, and renders one chart per pricing row so you can compare Plotly.js, D3.js, and Chart.js against the same monthly values.

Graphs not loaded yet.

Example HTML Page

This is the standalone HTML pattern for the selected preset: fetch the JavaScript engine, evaluate it, build the model from the scenario, then iterate across months and attributes with getValue(attribute, month).
