{"version":"1.0","type":"rich","title":"Assignment 6 - Manisha (Multi-Series Chart)","description":"This multi-series line chart compares average housing metrics across cities using normalized 0–100 values to share a single y-axis. The dark-themed SVG visualization plots three data series for average price, area, and bedrooms, sourced from a GitHub-hosted CSV file. The code aggregates the data with `d3.rollups`, sorts cities by name, and normalizes each metric against its maximum. Using `d3.scalePoint` for the categorical x-axis and `d3.scaleLinear` for the y-axis, it renders the lines, rotated tick labels, and a color-coded legend, all styled through D3 version 7’s standard API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be536be876fb492b9b501da99b6af84f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
