This bar chart visualizes the average expected goals (xG) for English Premier League teams, comparing home versus away matches. The data is loaded from a CSV file and processed using `d3.csv` and `d3.mean`. The visualization uses `d3.scaleLinear` and `d3.scaleBand` to map values, with bars rendered as SVG rectangles. A title and axes are added using `d3.axisLeft` and `d3.axisBottom`. The bars animate a color transition from steelblue to red using `transition`, while the page includes a video tutorial link. The rendering is SVG-based with dynamic interactivity.

AI-generated description

A 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 main function exported from index.js
  • The main function takes an argument container, a DIV that has measurable dimensions using clientWidth and clientHeight
  • The second argument to main is an options object containing state and setState.
  • The state of the application is stored in state, which is initialized as an empty object {}.
  • The setState function 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.

A4 - Scatter Plot

This scatter plot visualizes the relationship between total expected goals (xG) accumulated by football teams in home versus away games during a Premier League season. Each circle represents a team, positioned by aggregating home and away xG values via `d3.rollup` and `d3.sum` from CSV data. The visualization uses D3 v7 to create SVG axes with `d3.axisLeft` and `d3.axisBottom`, labels, and labeled circles, with hover effects defined in CSS.

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.

Making a Bar Chart

A bar chart displays the number of goals scored by Premier League players, with data from a local CSV file loaded via D3’s `csv` function. Steelblue rectangles represent each player’s goal count, with player names and values rendered as text. The visualization uses an SVG canvas, sized 960 by 500 pixels, and is built with D3 v5, selecting the SVG element and parsing the data through the `select` and `attr` methods.

Barchart-d3

This interactive bar chart displays goal and age data for ten Premier League players, sourced from a CSV file. Users can switch between these two attributes via a dropdown menu. The visualization uses D3 v5 scaleLinear and scaleBand for axes and bars, with a color legend driven by scaleSequential and interpolatePlasma. Hover interactions highlight bars in orange and display the numeric value overlaid as text, with a transition animation on mouseout reverting the fill.

Bar Chart: Goals

A bar chart compares total career goals for different footballers, with green bars animating upward in sequence from an initial zero position. The chart includes custom axes, rotated labels, and a football pitch overlay with field markings and penalty areas drawn behind the bars. It uses D3 v3 and v4 together, loading data from a CSV file, and relies on `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `selection.transition()` with duration and delay for the animated bar growth.

d3js workshop - animated bar charts

This animated bar chart visualizes the English Premier League standings as of February 2015, showing each team’s points and wins. Built with D3.js v3, it renders an SVG bar chart where bar lengths correspond to points, while bar colors and circular markers encode win counts on a blue-to-red scale. Clicking a bar or circle triggers a transition (via `transition.attrTween`-style updates) that switches the displayed metric, with text labels and tooltips revealing team names. The visualization reads data from a CSV file and uses `d3.scale.linear` for both position and color, with all elements rendered as SVG shapes.

d3js workshop - bar chart

This bar chart visualizes the English Premier League standings as of February 2015, showing each team’s total points. Using d3.csv to load the league table, it maps team names to horizontal bars whose widths are scaled linearly to the PTS column. The SVG rendering places team point totals at the end of each bar, with a fixed bar height and padding for clarity. The code relies on d3.scale.linear for the x-axis scale and d3 selection/enter/append patterns to construct the chart, though it does not include axes, labels, or interactivity beyond the static bars.

d3js workshop - bar chart

This example shows a horizontal bar chart of English Premier League standings, with each bar’s length representing a team’s total points and its color encoding the number of wins. The chart is rendered as SVG using D3 v3, reading team data from a CSV file via `d3.csv`. A linear `d3.scale.linear` maps points to bar widths and a second linear scale maps wins to a blue-to-red color range. Each bar is a `<rect>` inside a `<g>` group, with a text label showing the points value and a `<title>` element for hover tooltips.
