3e:null 3f:["$","title",null,{"children":"TP 3 — Encoder : de la donnée au dessin | Matias Verguet Bailly | Observable"}] 45:T48d,## Plot, canal par canal Un graphique Plot, c'est **des données + des marques + des canaux**. Un **canal**, c'est une variable visuelle. Voilà la table de correspondance — c'est le tableau du CM3, avec les noms de l'outil : | Canal Plot | Variable visuelle | Niveau perceptif | Ce qu'elle sait porter | |---|---|---|---| | `x`, `y` | **Position** | quantitative | tout — c'est la meilleure | | `r` | **Taille** | quantitative, mais mal estimée | des ordres de grandeur | | `fill` en dégradé | **Valeur** (clarté) | ordinale | un ordre, pas un rapport | | `fill` en teintes | **Couleur** (teinte) | sélective | des catégories, aucun ordre | | `symbol` | **Forme** | sélective | des catégories | | `opacity` | **Grain** | ordinale | un ordre grossier | **La règle du CM3, en une ligne :** on ne peut pas percevoir un ordre si la variable visuelle n'est pas ordonnée, ni un rapport si elle n'est pas quantitative. Le squelette d'un graphique : Plot.plot({ marks: [ Plot.barY(donnees, { x: "categorie", y: "valeur" }) ] }) `barY`, `dot`, `line`, `cell`, `rectY` : ce sont les **marques**. Ce qui est entre accolades : les **canaux**.46:T476, **À toi** **L'épreuve.** Pour chacun des quatre graphiques, réponds à trois questions — **sans regarder les chiffres**, en te fiant à ce que tu vois : 1. Peux-tu **classer** les régions de la plus fournie à la moins fournie ? 2. Peux-tu dire que **l'Île-de-France vaut le double** de l'Auvergne - Rhône-Alpes ? (C'est vrai : 521 contre 251.) 3. Peux-tu repérer **une** région précise en un coup d'œil ? Puis conclus : **quel encodage pour quel usage ?** *Ta réponse, dans la cellule ci-dessous.*47:T414,## Tes trois graphiques **À toi** Pour chacun : le graphique, puis **deux lignes** disant quelle variable visuelle porte quelle donnée, et à quel niveau perceptif. **G1 — une grandeur par catégorie.** Au choix : par région, par type d'établissement, ou par département. Contrainte : justifie ton encodage **et** ton tri. **G2 — deux variables à la fois.** Par exemple l'année d'ouverture et l'effectif, ou l'effectif selon le type. Contrainte : **deux canaux au moins**, et dis lequel porte quoi. **G3 — une distribution.** Celle des effectifs (`effectif`). Un histogramme suffit. Contrainte : avant de la tracer, va voir la cellule suivante.48:T4cb,`effectif` n'est rempli que pour **1 374 implantations sur 2 507** — 55 %. Mais regarde le tableau ci-dessus : **le taux de remplissage n'est pas le même selon le type**. Environ 58 % pour les universités, 36 % pour les grands établissements, 24 % pour les COMUE. **À toi** Deux questions : 1. Si tu additionnes la colonne `effectif` par type, **quel type est le plus désavantagé** par ce trou ? 2. Ce n'est donc pas du manquant « au hasard ». Comment appelles-tu ça, et qu'est-ce que tu écris sous ton graphique G3 pour être honnête ? *Ta réponse, dans la cellule ci-dessous.*49:[{"id":"0bc602383222f347c78dc2515ab79cf1d8058db3e9d1d918bbfb4e563db25ceefe086bbd947937e21ea0f732f2d965c10d2efe126186a7eb599cedefcb7e4a46","href":"https://static.observableusercontent.com/files/0bc602383222f347c78dc2515ab79cf1d8058db3e9d1d918bbfb4e563db25ceefe086bbd947937e21ea0f732f2d965c10d2efe126186a7eb599cedefcb7e4a46","name":"fr-esr-implantations_etablissements_d_enseignement_superieur_publics.json","type":"application/json","lastModified":1786309754302.429,"size":3727925}] 43:{"id":"5a32d0bd6649f9ee","slug":"tp-3-encoder-de-la-donnee-au-dessin","title":"TP 3 — Encoder : de la donnée au dessin","thumbnail":"a284768217a85af7db48e9f58cb12007313b0409cf698678919d42a8835de45f","access_level":"public","create_time":"$D2026-09-14T11:40:59.806Z","update_time":"$D2026-09-14T11:40:59.806Z","view_time":null,"first_public_time":"$D2026-09-14T11:41:08.061Z","has_unpublished_edits":null,"fork":{"id":"3c46a6326b55c60a","slug":"tp-3-encoder-de-la-donnee-au-dessin","title":"TP 3 — Encoder : de la donnée au dessin","owner":{"id":"29853dc62ffa3714","login":"mmi-montbeliard","name":"MMI Montbéliard"}},"stars":0,"starred":false,"owner":{"type":"team","id":"d6483012b4f06fee","login":"matiasverguet","name":"Matias Verguet Bailly","avatar_url":"https://avatars-next.observableusercontent.com/d8d84bee0e89a748bd0dd67e2e6f13b3bd4bf98c004d0511dd676cf10015bb31","tier":"starter_2024","bio":""},"version":191,"publish_version":191,"role":null,"authored":false,"authors":[{"type":"individual","id":"e30e4fc46f0171bb","login":"matiasverguet","name":"Matias Verguet Bailly","avatar_url":"https://avatars-next.observableusercontent.com/d8d84bee0e89a748bd0dd67e2e6f13b3bd4bf98c004d0511dd676cf10015bb31","tier":null,"bio":""}],"members":[{"type":"team","id":"d6483012b4f06fee","login":"matiasverguet","name":"Matias Verguet Bailly","avatar_url":"https://avatars-next.observableusercontent.com/d8d84bee0e89a748bd0dd67e2e6f13b3bd4bf98c004d0511dd676cf10015bb31","tier":"starter_2024","role":"editor"}],"comments":[],"custom_thumbnail":true,"trashed":false,"lapsed":null,"subscribed":null,"forks":1,"collection":null,"type":"notebook","body":{"titling":"auto","title":"TP 3 — Encoder : de la donnée au dessin","cells":[{"id":0,"value":"# TP 3 — Encoder : de la donnée au dessin\n\nNouveau jeu de données, et tu vas le garder jusqu'au TP 5 : **les 2 561\nimplantations de l'enseignement supérieur public en France**.
