This tree map visualizes the value of steel scrap exports from various countries, with each top-level rectangle representing a partner country and its total export value. The chart uses D3 v7’s `d3.hierarchy` and `d3.treemap` layout to render the hierarchical data as SVG rectangles. Clicking a country cell drills down to display the commodity-level breakdown for that country, using `transition` for smooth animated updates of the rectangles and labels. The data is loaded from a CSV file containing partner country, commodity description, and export values.

Ordered Tree Map with Drill down working

This interactive treemap visualizes steel scrap export values by partner country, with each country’s total represented as a colored rectangle. Clicking a country drills down to display its individual commodity categories as sub-rectangles, sized proportionally to their monetary values. The chart uses D3 v7’s `d3.hierarchy`, `d3.treemap`, and SVG rendering, with click-driven drill-down updates and smooth `transition()` animations on rectangle dimensions and labels. Data is loaded from a CSV file containing partnerCountry, commodityDescription, and Value fields.

Tree Map Example

This treemap visualizes steel scrap exports from partner countries, with each initial rectangle representing a country and its total export value. Clicking a country drills down to show a secondary treemap of that country’s commodity descriptions and their values. Built with D3 v7, the visualization uses `d3.hierarchy` and `d3.treemap` to compute the layout, rendering rectangles and labels as SVG elements. Data is loaded from a CSV file, and the drill-down interaction uses D3 transitions to animate the rectangle sizes and text updates over 500 milliseconds.

Tree Map Example

This interactive tree map visualizes the value of steel scrap exports from various countries, organized by destination country and then by specific commodity type. Each rectangle's area corresponds to the export value in dollars, providing a clear comparison of the trade volumes between categories. The visualization is rendered using the D3.js version 7 library, which constructs a hierarchical data structure from a CSV file and applies a treemap layout algorithm. The chart uses SVG for rendering rectangles and text labels, with the color palette consistently applying a single green tone to all nodes.

TreeMap with Tooltips and colors correctly

This treemap visualizes the total export values of steel scrap commodities by partner country, using a hierarchical layout where each country is a top-level branch and individual commodities become leaf cells. The diagram is initially aggregated to country level, but users can click any country cell to drill down and reveal its commodity breakdown, with a reset button to return to the overview. Cell size encodes total trade value, while color runs from light to dark blue via a sequential scale based on the maximum leaf value. The visualization is built with D3 v7, using `d3.hierarchy` for tree construction, `d3.treemap` for layout, and SVG transitions with 500-millisecond durations to animate changes between drill-down levels. Tooltips on each cell display either the country total or the commodity name and value, and text labels are wrapped to fit within each cell’s dimensions. Data is loaded from a CSV file containing partnerCountry, commodityDescription, and Value columns, representing U.S. steel scrap exports.

TreeMap with Tooltips

This tree map displays US steel scrap exports by partner country and commodity type, with each rectangle sized according to trade value. The visualization supports drill-down interaction by clicking on a country to reveal its commodity breakdown, plus a reset button to return to the top level. Built with D3 v7, it uses `d3.hierarchy` and `d3.treemap` to compute the layout, renders SVG rectangles with native tooltips via the `title` element, and animates resizing through `transition`. Data comes from an external CSV file containing country, commodity, and value columns.

TreeMap with Tooltips

This interactive tree map visualizes the hierarchy of steel scrap imports by partner country and commodity type. The hierarchical data is aggregated and rendered as nested rectangles using the D3.js treemap layout algorithm. Each country cell is color-coded and labeled, and clicking a country drills down to reveal its constituent commodity categories. Tooltips display the country, commodity, and value on hover, while a reset button restores the original view. The dynamic updates and transitions are implemented using D3's `transition` API within an SVG-based rendering.

Treemap Visualization

This treemap visualizes U.S. steel scrap trade values by partner country, with radio buttons to switch between Import and Export data. Each rectangle represents a country, sized and colored by total trade value, and clicking a cell drills down to show individual commodities. The visualization uses D3.js v7 with `d3.hierarchy`, `d3.treemap`, and `d3.scaleSequential` for color encoding, rendering SVG elements with interactive click handlers and animated updates. Data comes from a CSV file containing import/export records.

TreeMap Values Breaking

This interactive treemap visualizes steel scrap export values from various countries to different destinations. The size of each rectangular cell represents the total export value for a country, colored in a uniform green. Clicking a country cell drills down to show the breakdown of export values by specific commodity types, such as "Stainless Steel Waste And Scrap" and "Shredded Steel Scrap." The visualization uses D3.js v7 with the `d3.treemap`, `d3.hierarchy`, and transition animations to smoothly update the layout when drilling down or resetting.
