The diagram

• It follows the prize list from left to right: the year of the award, the category it was given in, and the composer who received it. It gathers 729 awards to 508 composers under 27 labels, across the 36 editions of 1973 to 2009. No competition was held in 1995.
• The diagram switch above gives two views of the same data. year → category fits one screen. year → category → composer adds the 508 composers and is some ten times taller. The page opens on the short one.
• Both views share their first two columns, and every total is the same in both. The short view holds 64 nodes and 194 flows, the full one 572 and 848.

The two years

• The awarded year is the year of the prize. The festival years are those in which the work was programmed at Bourges. The two usually coincide, and they need not.
• For 234 of the 729 awards no programming year is recorded at all. The festival mention is then simply omitted, which is an absence of evidence and not evidence of absence.

The columns and the flows

• The thickness of a flow is the number of awards it carries.
• Flows on the left run from a year to a category. In the full view, flows on the right run from a category to a composer.
• Colours only tell neighbouring flows apart. They carry no meaning of their own.
• The 38 awards recorded without a category are gathered under None. 34 of them fall between 1973 and 1976, when the competition still had a single ranking; the rest are the Pierre d'Or and Pierre d'Argent of 1999 and 2001, which reward a work of the repertoire and not an entry.
• The full prize list, work by work, is on the Award-winning works page.

Hovering and clicking

• Hover a flow on the left for what a category received that year: Programme, 1988 — 7 awards.
• Hover a node for what the diagram does not show. A year reads 31 awards in 6 categories, a composer 9 awards in 6 categories.
• A category opens with the period it covers, as in 1977-1998 — 79 awards to 66 composers, across 20 editions. That period is the one the competition declared, and editions counts the years in which it actually distinguished something. The two need not agree.
• In the full view, hover a flow on the right for the composer, the category and the years concerned: Robert Normandeau — 2 awards in Programme (awarded 1988, 1993 · festival 1988, 1993).
• In the full view, a name with a dotted underline has an ISNI, 397 of the 508. Click it to open the public authority record.

The categories

• Two nodes each carry two names, and the catalogue keeps both. Studio covers what the catalogue calls Électroacoustique in 1985–1991 and Studio in 1993–1998, the two bailiff's records that define it naming it alike. 1992 is empty inside that span without being a gap: the twentieth competition was open for one degree only, the Résidence, so it ranked nothing and had no category to name. Multimédia is the second such node, and it covers 1999–2009.
• A node marked ✦ is a distinction, not a category. The Magistère crowns a whole edition, and the Résidence is a residency offered rather than a ranked award. They carry 146 of the 729 awards, from 1988 on. They sit on this axis only because the printed catalogue puts them there.
• 12 categories were defined in 2000, from œuvre d'esthétique formelle to œuvre pour le multimédia. They carry 153 of the 729 awards.
