{"version":"1.0","type":"rich","title":"Radar chart","description":"This radar chart compares weekly usage percentages of 21 smartphone and tablet services, such as email, social networks, and online gaming, across two data series. It renders a multi-level circular grid with axis labels and value markers, using D3 v3’s selection and data join APIs to draw SVG polygons for each series. The chart supports click and double-click interactions that adjust fill opacity to highlight or reset series. A separate legend identifies the two devices by color, sourced from an ordinal color scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdb314b86c94418d8f771183520c03e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
