Forked from Pie Chart 11719939

This interactive tree visualizes EV charging stations grouped hierarchically by charger type, station operator, city, and station ID from a CSV data source. Users can click nodes to expand or collapse branches at each level. The D3 v7 implementation builds the hierarchy with `d3.group`, lays it out with `d3.tree`, and animates node movements and curved link transitions using `transition().duration()`. Colors differentiate depth levels, and zooming is enabled via the `d3.zoom()` API.

Network 11719939

This network graph visualizes electric vehicle charging stations, with nodes colored by charger type and linked when they share the same station operator. The layout is computed using d3.forceSimulation with forceLink and forceManyBody, while links are drawn as SVG lines and nodes as labeled circles. Data comes from a CSV file loaded via d3.csv, containing station IDs, operators, and charger types. The simulation updates node and link positions on each tick, producing a clustered view of operator relationships.

ICE8-Tree graph

This interactive tree diagram, titled "EV Data Based on Countries," visualizes a nested hierarchy of electric vehicle statistics. It displays a root node for overall EV data, which branches out to country-level nodes (Australia, Austria, Belgium), then to vehicle type categories (Cars, Buses, Trucks), and finally to powertrain types (BEV, PHEV, EV). The code constructs the visualization using D3.js version 7, and the page structure is defined in `index.html` with styling from `style.css`. The JavaScript builds the tree layout and renders it as SVG elements, with links styled as gray lines and circular nodes colored according to their level in the hierarchy.

line chart

This interactive line chart displays EV charging station metrics across stations, letting users toggle between charging ports, average charge time, daily users, and monthly energy consumption via a dropdown menu. The visualization uses D3 v7 to load CSV data from a GitHub gist, sort stations by ID, and render an orange line with red point markers. Smooth transitions animate point position updates when switching metrics, while hover tooltips reveal station details. The chart includes gridlines, axis labels, and a cleaned axis without domain lines.

Fork of Visualization of Spatial Data - Tree Graph

This interactive tree diagram visualizes hierarchical EV data by country, vehicle type, and parameter, with collapsible nodes that let users explore nested branches. Built with D3.js v6, the visualization uses `d3.hierarchy` and `d3.tree` to compute node positions, renders nodes as SVG circles with text labels, and draws curved links via path elements. Clicking a node triggers a smooth animated transition that expands or collapses its children, while branches beyond the second level start collapsed to reduce clutter. All rendering is SVG-based with CSS styling applied to node fills and cursor states.

plotting tree

This visualization displays 2011 EV stock values as a hierarchical tree chart, with countries (China, India, UK, USA) branching into vehicle categories (buses, cars) and then into BEV and PHEV types with labeled numeric values. The code uses d3.hierarchy and d3.tree to compute the layout, then draws cubic Bezier curves as links. Node and link colors are encoded directly in the JSON data structure, with SVG rendering and a linear-gradient CSS background.

Tree Graph ICE 8

This tree visualization displays the hierarchical structure of vehicle data, progressing from vehicle make down through model, fuel type, and transmission. The D3.js (v7) chart uses a tidy tree layout, with nodes colored according to their depth level—root in gray, makes in red, models in teal, fuel types in light green, and transmissions in yellow. The code builds the hierarchy from a CSV file using `d3.group`, constructs a tree structure, and renders it with `d3.hierarchy` and `d3.tree`, including the `d3.linkVertical` edge path generator.

area chart

This interactive area chart visualizes EV charging station metrics—charging ports, average charge time, daily users, and monthly energy—across station IDs. Built with D3 v7, it renders a smooth area path with an overlaid orange line and circular points, all using SVG. A dropdown menu lets users switch between metrics, triggering transitions that update the axes, grid, and data points. Hovering over a point reveals a tooltip with city details and the selected metric’s value, with data loaded from a remote CSV file.
