+FreezeLib can automatically detect the programming language:
+
+```go
+freeze := freezelib.New()
+
+// Automatic language detection from code content
+svgData, err := freeze.GenerateFromCodeAuto(code)
+
+// Detect language manually
+language := freeze.DetectLanguage(code)
+fmt.Printf("Detected language: %s", language)

+### Language Detection
+
+FreezeLib provides powerful language detection capabilities:
+
+```go
+freeze := freezelib.New()
+
+// Detect language from code content
+language := freeze.DetectLanguage(code)
+
+// Detect from filename
+language = freeze.DetectLanguageFromFilename("script.py")
