Figure 4
The chart presents a horizontal scale of qualitative strength levels mapped to numerical scores. The horizontal axis lists five categories from left to right: “Very Weak”, “Weak”, “Neutral”, “Strong”, and “Very Strong”. The vertical scale ranges approximately from negative 1 to 1, with intermediate labels including negative 0.5, 0, and 0.5. A diagonal line labeled “Score” connects the corresponding values for each category. The line begins at “Very Weak” with a score of negative 1, rises to negative 0.5 at “Weak”, reaches 0 at “Neutral”, increases to 0.5 at “Strong”, and ends at 1 at “Very Strong”. Vertical guidelines connect each category label to its corresponding score value on the diagonal line. Note: All the numerical data values are approximated.Classification of sustainable touristic cities
