{"version":"1.0","type":"rich","title":"Fork of  Assignment 10: B Grade","description":"This example shows a bar chart of yearly values from a small CSV dataset, displaying four data points from 2015 to 2018. The visualization uses D3 v3’s ordinal scale with rangeRoundBands for the x-axis and a linear scale for the y-axis, rendering bars as SVG rectangles. It employs d3.svg.axis for both axes, with rotated tick labels on the x-axis, and parses dates using d3.time.format. The chart loads data via d3.csv and uses the height–y(val) calculation to size each bar’s height proportionally to its value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bc5251371844ef48d27113495e9357c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
