The visualization tracks New York City’s annual water consumption from 1979 to 2009, contrasting total daily use in million gallons with per-capita gallons. It shows a clear downward trend in both metrics over three decades. The code uses D3.js with `d3.csv` to parse the gist-sourced CSV, then renders a dual-line chart via SVG paths and scales (`d3.scaleLinear`, `d3.line`). Hovering triggers a tooltip with `d3.mouse` and `transition.attrTween` for smooth updates, while axes are generated with `d3.axisBottom` and `d3.axisLeft`. The raw data is loaded directly from the linked `Water_Consumption_In_The_New_York_City.csv` file.

Water Consumption NY

This visualization tracks New York City’s daily water consumption from 1979 to 2009, comparing total millions of gallons used against per-capita gallons. It uses D3.js v3 with SVG circles and transitions, animating the data points into a sorted scatterplot along time-based axes. The chart relies on d3.csv, d3.svg.axis, and d3.scale.linear, with hover effects and animated reordering. The dataset, sourced from DATA.GOV via a Gist, is rendered on a light blue background with a clean, minimal aesthetic.

Water Consumption NY

The visualization shows how New York City’s water consumption changed over time, comparing total millions of gallons per day against per-capita gallons per person per day. It uses D3 v3 to render an SVG scatterplot where each circle represents a year, with hover tooltips and a sort-then-animate transition that reveals the chronological order. The x-axis and y-axis are drawn using `d3.svg.axis`, while the data is loaded from a CSV file and mapped through linear scales. The circles animate from large gray markers to smaller dark ones, highlighting the downward trend in both metrics from 1979 to 2009.

Water Consumption NY

This bar chart shows New York City’s daily water consumption from 1979 to 2009, with each bar’s width representing millions of gallons used per day. Sorted in descending order by year, the chart highlights a general decline in consumption over time. The visualization uses d3.v3 with SVG rendering, loading data from a CSV file via `d3.csv`. Bars are drawn as `rect` elements, with widths scaled directly from the numeric values and hover effects using CSS `fill-opacity` and a white fill. The data source is the provided CSV, which includes both total consumption and per-capita figures.

Water Consumption NY

This horizontal bar chart shows New York City’s annual water consumption from 1979 to 2009, with each bar representing a year’s average million gallons per day. It uses d3.csv to load the data, d3.scale.linear and d3.scale.ordinal for positioning, and d3.svg.axis for both axes. Rectangles render as SVG bars with hover tooltips via the title element, while the x-axis measures consumption and the y-axis lists years in descending order. The source is DATA.GOV, and the design emphasizes the overall decline in usage over time.

Loading CSV Data with D3

This example demonstrates how to load a CSV file containing New York City water consumption data and log it to the browser console using D3.js v3. The page features a static, decorative SVG illustration of a water-themed icon alongside the heading "Water Consumption In New York City." The core functionality relies on the `d3.csv` method to asynchronously fetch and parse the external CSV file into an array of JavaScript objects. No chart is rendered from the data; instead, the visualization focuses on showcasing the data-loading process, with the console serving as the output for the parsed dataset.

Water Consumption In New York City

The visualization displays New York City’s water consumption across years, mapping population against total daily water use, with each circle’s size encoding per-capita gallons per day. It shows how consumption metrics change over time while allowing interactive inspection via hover tooltips that reveal exact values for year, population, and water usage. Built with D3 v4, it uses `d3.scaleLinear` for axes and radius, `d3.axisBottom` for the time axis, and underscore templates for tooltip content. Data comes from NYC OpenData, rendered as SVG circles with mouseover events.

Water Consumption In New York City v2

This visualization plots New York City’s annual water consumption data as a scatterplot, with each circle representing a year. The x-axis shows the year, while the y-axis maps population, and the circle radius encodes average gallons of water used per person per day. Hovering over a circle reveals a tooltip with the year, per-capita usage, total million gallons per day, and population. The chart uses D3 v4 with SVG rendering, scales for positioning and radius, and a template for the tooltip. Data comes from the NYC OpenData portal.

VP Iteration on First Visual

This D3.js visualization displays New York City water consumption and population data from 1979 to 2022. It plots two lines over time: one black line for water consumption (in millions) and one red line for population, each scaled to its own y-axis using `d3.scaleLinear`. The SVG chart is rendered with `d3.line` for the paths, `d3.axisLeft` and axis label helpers from `@curran/axis-labels`, and a light gray inner rectangle background. Data originates from the NYC Open Data water consumption dataset.
