Bir Postgres veri tabanından veri çeken ve bunları bir grup güzel Google Grafik olarak görselleştiren bir JS komut dosyası hazırladım. Bu iyi çalışıyor, ama çok yavaş ve bazen web sayfası sadece zaman aşımına uğradı.Google Grafiksel bir sunucu tarafında sakla
Düzeltmek için grafikleri PNG/GIF/SVG/Whatever olarak oluşturmayı düşünüyordum ve belirli aralıklarla grafikleri yenilemek için bir cron işi kullanın. Bu, hız için etkileşimi (bu durumda çok önemli olmayan) kurban ederdi. Bununla birlikte, bir Google arama, PHP ile Google grafikleri oluşturmak için açık bir yol sağlamaz. Baska öneri? İşte
