{"version":"1.0","type":"rich","title":"Using d3-tip to add tool","description":"This example shows a bar chart of letter frequencies from a TSV dataset, where hovering over a bar triggers two visual effects: a purple highlight and a custom tooltip displaying the frequency value. The chart uses d3.v3 with SVG rendering and animated transitions. Tooltips are implemented with the d3-tip library, while an additional HTML div tooltip follows the mouse position. The bars animate into place with an elastic easing effect on load, and the axis uses a percentage format.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7e8f43fc4f2e6e715a8ec172e44cb2e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
