Forked from Fork of Making an Interactive Pie Chart

This interactive pie chart visualizes university funding amounts, with each slice labeled and color-coded by institution. Built with D3.js v5, the chart uses `d3.pie` and `d3.arc` to generate the donut geometry and `d3.scaleOrdinal` with `d3-scale-chromatic` for slice colors. Hovering over a slice triggers a tooltip showing the percentage of total funding, calculated via `d3.sum` and `d3.event`. The data comes from a CSV file loaded asynchronously, and the visualization renders as SVG with hover opacity effects and rounded slice corners.

Fork of Making an Interactive Pie Chart

This interactive donut chart displays the number of university students at ten institutions, with each slice labeled and colored using a custom ordinal scale from d3-scale-chromatic. Hovering over a slice reveals a tooltip showing the percentage of total enrollment. Built with D3.js, the visualization uses d3.pie, d3.arc, and d3.select to compute slice geometries and handle mouse events, rendering as SVG. Data is loaded from a CSV file containing university names and student counts.

This interactive donut chart displays the distribution of student enrollment across ten prominent universities, with each slice labeled and color-coded. Hovering over a slice reveals the percentage of total students it represents via a tooltip. The visualization uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with a custom color range from `d3-scale-chromatic`, while rendering SVG elements and tooltip interactions are managed through D3 selections. Data is loaded from a CSV file.

Making an Interactive Pie Chart

This interactive donut chart visualizes income sources (Sales, Dividends, Interest) from a CSV file, with each slice’s arc length proportional to its amount. Hovering a slice reveals a tooltip showing its percentage of the total, computed via `d3.sum`. Built with D3 v5, it uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` for coloring, and renders as SVG with hover effects and a styled tooltip.

Making an Interactive Pie Chart

This interactive donut chart displays income sources—Sales, Dividends, and Interest—with each slice labeled and colored via a d3.scaleOrdinal. It uses d3.pie and d3.arc to generate the SVG paths, while mouseover events calculate percentages from the CSV data and reposition a tooltip with d3.select. The chart responds to hovers by increasing slice opacity and shows precise share values, with styling in CSS.

Making an Interactive Pie Chart

A donut chart displays income categories with a tooltip showing percentage on hover. The visualization uses D3 v5’s `pie`, `arc`, `scaleOrdinal`, and `csv` functions to load income data and render SVG paths. Labels are positioned using the `labelArc.centroid` method, while tooltips appear via mouseover events and are hidden on mouseout, with interaction handling for both slices and the tooltip itself.

Fork of Making an Interactive Pie Chart

This donut chart displays the proportional breakdown of income sources, with three colored segments labeled Sales, Dividends, and Interest. Hovering over a slice reveals a tooltip showing its percentage of the total amount. The visualization uses D3 v5 APIs including `d3.pie`, `d3.arc`, `d3.scaleOrdinal`, and `d3.sum` to calculate and render the arcs. Data is loaded from a CSV file, and the SVG elements are manipulated directly to create the chart and interactive tooltip.

Fork of Making an Interactive Pie Chart

This interactive donut chart displays the distribution of income across three categories—Sales, Dividends, and Interest—from a CSV file. The visualization uses D3 v5’s `pie` and `arc` APIs to generate the donut segments, with a `scaleOrdinal` color scale for category distinction. Hovering over a slice triggers a tooltip, implemented via D3’s `select`, showing the percentage contribution of that category, calculated with `sum` from the data’s amount field. The SVG rendering includes labeled text for each slice, and slices are interactive with `mouseover` and `mouseout` events.
