This example visualizes health survey data across time periods using a series of overlapping, semi-transparent rectangles. The bars are positioned along a time axis from the start to the end date of each survey, with their height reflecting the reported percentage value. A red line connects the midpoints of these intervals to highlight the trend over the years. The visualization is rendered as an SVG using React and D3.js v6, specifically employing `d3.scaleTime`, `d3.scaleLinear`, `d3.line`, and JSON data loading via `d3.json`.

Overlapped Barchart6.1

This example shows a time-series bar chart overlapped with a line graph, plotting five survey data points over a roughly 15-year span. Each bar represents a survey period’s start and end dates, with its height indicating the percentage value. The red line connects the middle date of each period to its value. The visualization uses React for rendering and d3.scaleTime, d3.scaleLinear, and d3.line to generate the SVG elements. Data comes from the local JSON file `timeperiodv2.json`.

Overlapped Barchart

This visualization uses a React component to render an overlapped barchart in SVG, displaying percentage values across five time periods from survey data. The code loads JSON data via d3.json, then constructs scales with d3.scaleBand and d3.scaleLinear to map time periods and values to x and y coordinates. Overlapping bars are drawn as semi-transparent green rectangles with rgba(200,255,220,.9) fill, allowing underlying bars to show through when values decrease over time. The chart omits axis labels and focuses solely on the bar geometry, with data sourced from the timeperiod.json file.

Overlapped Barchart8

This example visualizes survey data as a time-series line chart overlaid with semi-transparent rectangle bars representing each survey period. It uses D3’s scaleTime and scaleLinear for axes and a line generator for the trend line. The React app fetches `timeperiodv2.json` and displays tooltips on mouseover, with animated opacity transitions, highlighting each period’s name and value. SVG rendering draws the bars, axes with ticks, and labels directly above each bar.

Overlapped Barchart3

This visualization displays five time periods as overlapping horizontal bars on a timeline, with each bar's width representing the date range and height reflecting the data value (a percentage). The chart uses React to manage state and D3 v6 APIs (`d3.json`, `d3.scaleTime`, `d3.scaleLinear`) to parse dates from a JSON file (`timeperiodv2.json`) and map them to SVG rectangles. The bars, drawn in semi-transparent green, overlap to highlight how different survey periods (e.g., NFHS3, RSOC, CNNS) compare chronologically and by value, while axes and grid lines are generated from D3’s tick functions.

Overlapped Barchart4

This visualization shows how a percentage value changes across overlapping time periods, with each period's range displayed as a bar and the trend emphasized by a red line connecting the midpoints of each period. It combines a time-based bar chart with a line overlay to reveal the downward trend in the data. The chart is built using React to manage the loading and transformation of the JSON data, while D3.js functions like `scaleTime`, `scaleLinear`, and `line` handle the coordinate scaling and path generation. SVG rectangles are positioned using each period’s start and end date, and the line uses the calculated middle date of each period.

Overlapped Barchart7

This example combines a timeline bar chart with an overlaid line graph to show changes in percentage values across five survey periods from 2005 to 2020. Each green bar spans its corresponding date range, with labels above and hover tooltips revealing exact start and end dates. A green path, generated using `d3.line`, connects the bar midpoints to emphasize the downward trend. Built with React and `d3.scaleTime` and `d3.scaleLinear`, the SVG renders axes, ticks, and bars from the timeperiodv2.json data, with `d3.timeParse` handling date conversion and CSS transitions animating tooltip opacity.

Overlapped Barchart9

This visualization overlays a semi-transparent bar chart and a line graph to show changes in a percentage metric across overlapping time periods, with each bar labeled and tooltips revealing start and end dates. The React app loads JSON data containing survey periods (e.g., NFHS3, NFHS5) and uses d3.scaleTime, d3.scaleLinear, and d3.line to draw SVG elements. Animated hover interactions are handled via React’s onMouseOver and onMouseOut, while d3’s selection API manages the tooltip’s opacity transitions.

Fork of Overlapped Barchart2

This example uses a React component with D3 to visualize survey period overlaps as a horizontal time-series bar chart. Each rectangle’s x-position and width map to a survey’s start and end dates using `d3.scaleTime`, while its height represents the reported percentage via `d3.scaleLinear`. The SVG bars are drawn from `timeperiodv2.json`, which provides start and end dates parsed with `d3.timeParse`. The chart displays five national surveys from India, showing how their data collection periods overlap across time.
