Forked from Lesson 3

An interactive multi-bar chart displays synthetic stream data across time, with controls for filtering by year, month, week, and zoom level. The visualization uses the NVD3 library’s `multiBarChart` model with D3.js v3 for rendering and transitions. Sidebar selectors and buttons adjust the view, while radio buttons switch between yearly, monthly, weekly, and daily granularity. Data is generated dynamically via custom `stream_layers` and `stream_waves` functions, producing three random series with bump-based distributions.

Lesson 3

An interactive stacked bar chart displays purchase quantities of various grocery items across years, with controls for filtering by year, month, or week. The visualization uses NVD3’s `multiBarChart` with stacked bars, driven by D3.js for rendering and transitions. Data comes from a local JSON file containing product names and yearly values, while a sidebar offers radio buttons and dropdowns to adjust the temporal granularity. The chart updates its axes and bar groups based on the selected period, integrating SVG rendering for crisp visuals.

Lesson 3

This interactive chart visualizes the purchase quantities of various grocery items across different years. Users can filter the data by year, month, or week using dropdown menus and navigation buttons, while radio buttons control the zoom level (yearly, monthly, weekly, or daily). The visualization is rendered as a stacked multi-bar chart using the NVD3 library with D3 v3, displaying SVG elements with smooth transitions. The data is loaded from a local JSON file containing product names and their corresponding values for each time period.

Lesson 3

This example uses D3 v5 within a React framework to render a bar chart as an SVG, displaying population data from the World Bank for selected countries. The chart encodes population values with bar heights. The code loads data from a CSV file and uses D3’s selection and scaling APIs to map the data to the chart’s coordinates. The SVG is styled with CSS rules from an external stylesheet, defining colors for bars, text, and axis elements. The visualization demonstrates how to transition from a raw data source to a clean, client-ready presentation.

MasteringD3js_Ch2 pt2.2

This example demonstrates three versions of an interactive barcode chart that visualizes event timestamps as vertical lines on a timeline, with buttons to add new data points using an exponential random interval generator. The first chart shows basic updates, the second addresses transition smoothing, and the third refines bar removal. Built with D3 v5, the code uses `d3.scaleTime`, `d3.timeDay`, and `d3.dispatch` for time-domain mapping and custom event handling, rendering SVG elements with enter/update selections and animated transitions. The dataset consists of JavaScript `Date` objects generated client-side.

barChart and pieChart V3

This example shows how interactive bar charts and pie charts can be built with React and D3 v5, allowing users to switch between chart types and select different categorical columns from a dropdown menu. The visualization displays absolute frequencies of student grades and degree programs, with hover tooltips showing values or percentages, and animated transitions when switching data. It uses D3’s scaleBand, scaleLinear, scaleOrdinal, nest, pie, arc, and axis components, rendered as SVG with transitions and animation delays, plus custom tooltip handling via mouse events.

Lesson 3

This visualization presents a horizontal bar chart comparing population data across several countries, sourced from the World Bank. The chart displays both X and Y axes with clear labels, a chart title, and bars colored in steelblue. The code uses `d3.csv` to load the data, along with `scaleLinear` and `scaleBand` for scaling, and `axisLeft` and `axisBottom` to render the axes. SVG rendering is handled within a React framework.

Barchart

This example shows an interactive bar chart with multiple data series that can be toggled between grouped and stacked layouts via radio-button style controls. Additional buttons allow users to show or hide individual series. The visualization uses D3 v6 with SVG rendering and animated transitions, employing `d3.stack` to compute stacked values and `d3.scaleBand` and `d3.scaleLinear` for positioning. Data is generated procedurally using smooth random bumps, and mouseover interactions display tooltips with precise values.

D3 Bar Chart

This interactive D3 v4 bar chart displays two datasets of numbers as vertical steel-blue bars with value labels and a y-axis. Clicking the Update button toggles between a 10-element ascending dataset and an 8-element descending one, demonstrating the enter, update, and exit pattern. The code uses d3.scaleLinear for the y-scale, d3.axisLeft for the axis, and transition().duration(500) to smoothly animate bar heights, positions, widths, and labels when the data changes. SVG rendering handles all visual elements.
