Inline sparklines embed a compact line chart directly within a paragraph of text, showing a time series of three different measures (amount1, amount2, and amount3) from a CSV dataset. Each sparkline displays six yearly data points, with its own y-axis scale and end-label showing the latest value and percent change from the prior year. The visualization uses D3.js version 3.5, including `d3.csv`, `d3.nest`, `d3.svg.line`, and `d3.scale.ordinal`, and is rendered as inline SVG elements. Data is reshaped from wide to long format before being fed into a reusable `sparkline()` function.
