{"version":"1.0","type":"rich","title":"Multi-Series Line Chart","description":"This multi-series line chart visualizes the frequency of seven emotions (Gioia, Rabbia, Sorpresa, Disgusto, Paura, Tristezza, Fiducia) from 1950 to 2010, with each emotion represented as a separate colored line. The data is loaded from a TSV file and parsed using d3.tsv, with dates parsed via d3.time.format. The visualization uses d3.time.scale for the x-axis, d3.scale.linear for the y-axis, and d3.scale.category10 for color encoding. Each emotion is rendered as a basis-interpolated line using d3.svg.line, with axis labels and legends positioned using conventional margins. The y-axis is labeled \"Frequenza (tf-idf)\".","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-f1bd1f87cee73a08027994059fffa906?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
