A4 - boxPlot
This example visualizes the total expected goals (xG) accumulated by football teams in home games using a box plot. The chart displays the distribution of these values across all teams, with the box representing the interquartile range and whiskers extending to the minimum and maximum within 1.5 times the IQR. The code loads CSV data from a GitHub gist using `d3.csv`, aggregates values with `d3.rollup`, and computes quartiles with `d3.quantile`. The visualization is rendered as SVG using D3 scales, axes, and shape primitives.
AI-generated descriptionA blank slate starting point showing the "Hello World" for the VizHub V3 Runtime Environment, which supports continuous hot reloading with interactive widgets.
- There is no
index.html- that's what triggers the V3 Runtime - The entry point is the
mainfunction exported fromindex.js - The
mainfunction takes an argumentcontainer, a DIV that has measurable dimensions usingclientWidthandclientHeight - The second argument to
mainis an options object containingstateandsetState. - The state of the application is stored in
state, which is initialized as an empty object{}. - The
setStatefunction can be called with a function that uses the previous state to create a new state object using immutable update patterns. - For an interactive example, see Mouse Follower.
