{"version":"1.0","type":"rich","title":"d3 | keypress keyboard events","description":"This example demonstrates Japanese number characters (zero through nine) and their readings, which update interactively when a user presses a number key or clicks a button. Built with D3.js v3, it binds keyboard events using the Mousetrap library and handles button clicks through D3 selections and the Lodash `times` helper. The `update` function uses D3’s `select` and `html`/`text` methods to change the displayed character and reading, while adjusting button opacity to highlight the active selection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0158141680b04b5696156ff2a855c3bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
