Mountain Car Ortamını Görselleştirme

Şimdi, Mountain Car ortamını keşfetmede bir adım daha ileri gideceksin. Görselleştirme, RL ortamlarının dinamiklerini anlamanın kilit bir parçasıdır. Ortamın mevcut durumunu gösteren bir render() fonksiyonu yazacaksın. Bu fonksiyonu, görselleştirmek istediğin herhangi bir ortam için daha sonra da kullanacağız.

matplotlib.pyplot ve gymnasium sırasıyla plt ve gym olarak içe aktarılmıştır.
