{"version":"1.0","type":"rich","title":"Fork of D3.js Line Chart","description":"This chart shows the trend of Happiness Scores for China, India, and Japan over five years, drawing on data from the World Happiness Report. A single line is rendered using an SVG path generated by the D3.js `d3.line` function. The x-axis uses an ordinal scale (`d3.scaleBand`), while the y-axis is a linear scale (`d3.scaleLinear`); both axes are created with `d3.axisBottom` and `d3.axisLeft`. The visualization aggregates the data to show the overall score trajectory, though it does not distinguish between the three countries in its line presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab72e564969c44e9a011f3e9c5237978?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
