Figure 7
The radar (spider) chart illustrates the sustainability performance of tourism in Surakarta across several indicators. The chart is circular and divided into six axes, each representing a different tourism-related indicator. At the top axis, the label reads “Daily intensity of tourist use”. Moving clockwise, the other axes are labeled “Pollutant emissions”, “Contribution to G D P”, “Employment contribution”, “Hotel occupancy”, and “Social-carrying capacity”. The chart contains three colored datasets, each represented by circular markers connected with dashed lines: the orange markers and dashed line represent Economy indicator, the blue markers and dashed line represent Social indicator, and the green markers and dashed line represent Environmental indicator. Concentric colored rings form the background, representing different value ranges from the center outward. Numerical values along the axes include negative 1, negative 0.5, 0, 0.5, and 1, indicating the normalized scale used for comparing indicator performance. Across the axes, the three categories show different patterns: The economic indicators (orange) extend relatively outward toward the axes for Contribution to G D P with a value near 0.9, Pollutant emissions with the value near 0.2, Hotel occupancy with the value near 0.4, Social-carrying capacity with the value near 0.6, Daily intensity of tourist use with the value near negative 0.3, and Employment contribution with the value near negative 0.2. The social indicators (blue) show moderate values across the axes, with Pollutant emissions near 0.4, Contribution to G D P near negative 0.1, Employment contribution near negative 0.4, Hotel occupancy near negative 0.4, Social-carrying capacity near 0.9, and Daily intensity of tourist use near negative 0.4. The environmental indicators (green) extend outward on Pollutant emissions with a value near 0.6 and Social-carrying capacity with a value near 0.8, while showing Contribution to G D P near 0, Employment contribution near negative 0.25, Hotel occupancy near negative 0.4, and Daily intensity of tourist use near negative 0.3. At the bottom center of the figure, the label “SURAKARTA” identifies the location being analyzed. Below the chart is a legend showing the color mapping: orange equals Economy, blue equals Social, and green equals Environmental. Note: All the numerical data values are approximated.STC metrics for the city of Surakarta
