Cette biblioth\u00e8que est bas\u00e9e sur la <\/span><b>grammaire des graphiques<\/b><span style=\"font-weight: 400;\">, qui permet de d\u00e9crire des graphiques en termes de composants de base tels que des axes, des l\u00e9gendes ou encore des \u00e9tiquettes.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">Ainsi, avec ggplot on peut voir un graphique comme une <\/span><b>s\u00e9rie de couches<\/b><span style=\"font-weight: 400;\"> qui se superposent pour produire le graphique final. Chaque couche de graphique peut \u00eatre ajout\u00e9e \u00e0 l&rsquo;aide de la fonction <\/span><b>+<\/b><span style=\"font-weight: 400;\"> et peut inclure des \u00e9l\u00e9ments tels que des points, des lignes, des barres, des nuages de points, des histogrammes, des bo\u00eetes \u00e0 moustaches, des textes et bien plus encore.<\/span><\/p><p><span style=\"font-weight: 400;\">Pour cr\u00e9er un graphique \u00e0 l&rsquo;aide du syst\u00e8me de couches sur ggplot, commencez par sp\u00e9cifier les donn\u00e9es et les variables \u00e0 utiliser pour les axes x et y, puis ajoutez progressivement des couches de graphiques suppl\u00e9mentaires.<\/span><\/p><p><span style=\"font-weight: 400;\">L\u2019une des couches de graphique les plus utilis\u00e9es est celle de
