Évolution des genres

Encoding note (rough): data item = one genre-year aggregate after filters. Mark used = stacked area, chosen because it combines temporal continuity with part-to-whole composition in a single view. Visual variables: x-position maps year, y-height maps track count (or share when normalized), and color hue maps genre.

Encoding note (rough): data item = one language aggregate in the selected period. Mark used = radial ring segments (custom SVG, CD metaphor), chosen to match the music theme and to let users compare composition shares while directly interacting with language segments. Visual variables: angular span maps share/volume, hue maps language, and opacity indicates selected vs non-selected languages.

Encoding note (rough): data item = one genre aggregate in the current selection. Mark used = inline horizontal bars in an HTML table-like list, chosen because bars make rank and magnitude comparison immediate in compact summary space. Visual variables: bar length maps relative volume versus the top genre, text labels carry exact counts, and bar color maps genre.

Durée moyenne par langue

Encoding note (rough): data item = one language-year record. Mark used = multi-series line + dots, chosen because lines emphasize continuous evolution and dots keep individual yearly observations readable. Visual variables: x-position maps year, y-position maps average duration (minutes), and color hue maps language.
