Crime data

A radial bar chart visualizes the relationship between student grades (A, B, C) and anxiety levels, using concentric rings where each ring represents an anxiety level and arc length encodes the count of students. The chart is built with D3 v7, using the `d3.arc()` API for the radial segments and `d3.scaleOrdinal()` for color encoding by grade. Data is loaded from a CSV file, with grid lines and axis labels indicating anxiety levels. Hovering over a segment reveals a tooltip showing the exact count.

Fork of Viz Function Concept

This dashboard visualizes Boston incident data from a CSV file using three D3.js v7 charts: a bar chart of offense types, an area chart showing hourly incident distribution, and a pie chart of incidents by district. The code uses `d3.rollup` to aggregate the data, `d3.scaleBand` and `d3.scaleLinear` for the bar and area charts, and `d3.area` with `d3.curveMonotoneX` for the hourly trend. Each chart renders as SVG within responsive cards that update their layout at different screen sizes.

Visualisation GDP

This example presents a multi-chart dashboard visualizing global GDP, population, CO2 emissions, and agricultural data. It loads CSV data from a GitHub repository and renders separate bar, line, histogram, and scatter charts using the Chart.js library. The code also includes custom D3.v5 functions for violin, density, histogram, and boxplot plots, which are defined but not directly invoked in the main HTML, where charts are drawn on canvas elements.

graphs

This visualization displays country-level economic and health indicators, including a line chart of GDP values, a histogram of GDP distribution, and a scatter plot comparing GDP with life expectancy. The code loads CSV data, cleans GDP strings, and initializes three chart instances using the Chart.js library alongside D3.js for data fetching. The charts render on separate HTML canvas elements, with the line chart displaying raw GDP values and the scatter plot revealing correlations between economic output and longevity.
