Sparks: A Typeface for Creating Sparklines in Text

After the Flood, a design consultancy, has released Sparks, a new typeface that leverages OpenType's contextual alternates feature to generate sparklines directly within text. By inserting data points in a specific format between numbers (e.g., `123{30,60,90}456`), users can create sparklines. Sparks is compatible with various browsers and software, offering bar, dot, and dot-line styles with five weight variations. While the underlying mechanism is complex, it offers a novel and convenient method for data visualization.
