Forked from Fork of Making an Interactive Pie Chart

This interactive donut chart visualizes income breakdown across three categories—Sales, Dividends, and Interest—using repeated rows from a CSV file. Built with D3 v5, it renders an SVG donut with labeled slices and a hover tooltip displaying each category’s percentage. The code leverages `d3.pie` for arc calculation, `d3.arc` for path geometry, and `d3.scaleOrdinal` for color mapping. Hovering highlights a slice and dynamically positions a tooltip using mouse coordinates.

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.

Fork of Fork of Making an Interactive Pie Chart

This donut chart displays income categories (Sales, Dividends, Interest) with each slice’s percentage revealed via an interactive tooltip on mouseover. Built with D3 v5, it loads data from data.csv, scales colors with `scaleOrdinal`, and computes slice geometry using `pie` and `arc` functions. Hovering highlights each slice’s opacity change and shows a tooltip positioned at the cursor, while labeled text sits inside each arc segment. The SVG rendering includes a padded, rounded arc style with corner radius.

Fork of Making an Interactive Pie Chart

This interactive donut chart displays the proportion of income from Sales, Dividends, and Interest, with each slice labeled by category and showing a percentage on hover. Built with D3 v5, it uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate SVG paths, while tooltips are implemented via mouse events and a styled HTML div. The chart reads its data from a CSV file, computing percentages from the parsed values, and features rounded slice corners and a responsive hover opacity effect.

Fork of Making an Interactive Pie Chart11

This donut chart displays the relative proportions of three income sources—Sales, Dividends, and Interest—loaded from a CSV file. Each slice is labeled with its category name and colored using a custom ordinal scale. The visualization uses D3 v5’s `pie` and `arc` generators to compute slice geometry and `scaleOrdinal` for coloring. Hovering over a slice triggers an interactive tooltip that calculates and displays the percentage of the total amount represented by that slice, using `d3.sum` for aggregation and event listeners for mouse interactions.

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.

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 distribution across Sales, Dividends, and Interest using a D3 pie layout and arc generator. Hovering over a slice reveals a tooltip showing the percentage of the total amount, calculated with d3.sum. The chart uses a color scale with ordinal colors, labels positioned via arc centroids, and SVG rendering. Data is loaded from a CSV file, and the tooltip fades in and out based on mouseover and mouseout events.
