This example uses a multi-series line chart to compare hours studied, sleep hours, and exam scores for each student, allowing viewers to spot trends across the dataset. The D3.js code loads a CSV file, dynamically detects column names, and renders three colored lines on a shared axis. It employs `d3.dsvFormat` for parsing and `d3.select` for SVG manipulation, with a custom legend indicating each series. The chart is rendered as an SVG with a dark theme and styled axes.

Multi-Series Line Chart

This multi-series line chart examines the relationships between study hours, sleep hours, and exam scores for 187 students. The visualization displays three trends on a shared axis, with each series represented by a distinct color. Built with D3.js v7 and rendered as an SVG, the code uses `d3.text` and `d3.dsvFormat` to efficiently parse the comma-delimited CSV data file. The chart automatically detects column names and scales, providing a clean overview of how these academic factors correlate with performance.

Q3 D3 Starter - Dinesh

This example displays a multi-series line chart tracking student performance across 200 weeks, plotting study hours, sleep hours, and exam scores on a single y-axis. The D3 v7 code loads data from a CSV file and uses `d3.line` with `curveMonotoneX` to generate smooth paths for each metric, with circles marking individual data points. Axes and gridlines are rendered via `d3.axisLeft` and `d3.axisBottom`, while a legend distinguishes the three colored series. The visualization employs an SVG-based rendering approach with a white background and styled grid lines.

Combined Chart

This combined chart displays average study hours as bars and average exam scores as a line, grouped by sleep-hour bins. It uses `d3.rollups` to aggregate the CSV data and a dual-axis layout with an SVG render. The chart is built with D3 v7, featuring flexible column detection and dark-themed styling.

StudentScore_ScatterPlot

This scatter plot visualizes the relationship between hours studied and exam scores for ten students. The chart displays a clear positive correlation, with data points plotted on a linear scale for both axes. Built with D3.js v7, the visualization loads data from a CSV file using `d3.csv` and constructs an SVG with `d3.select` and `append`. The code creates scales with `d3.scaleLinear` and renders axes via `d3.axisBottom` and `d3.axisLeft`. The reusable `scatterPlot` function applies steelblue, semi-transparent circles to represent each student's data.

shish's multiseries line and combined chart

This example presents two linked visualizations of a sleep health dataset: a multi-series line chart and a combined chart. The line chart plots Age against Sleep Duration, Stress Level, and Daily Steps using d3.line with d3.scaleLinear axes, while colored dots and tooltips show exact values. The combined chart reuses the same scales and color encoding to display the data differently. The code loads data via d3.csv, applies SVG rendering, and includes interactive mouseover events with tooltip transitions.

Scatter plot

This dark-themed scatter plot visualizes the relationship between hours studied and exam scores for 188 students, with each point colored by attendance percentage using a sequential turbo scale. The visualization loads data from a CSV file and renders it as SVG circles, employing D3 v7 scales for positioning and color encoding. Interactive tooltips display student details on hover, while grid lines and axis labels provide context for the academic performance metrics.

ICE6_TASK_2

This example renders a scatter plot of student exam data, showing hours studied against previous scores while using sleep hours to drive a sequential turbo color scale. The visualization, built with React and D3 v7, loads CSV data from a remote GitHub gist and renders points as SVG circles. Hover interactions display a tooltip with each student’s attendance percentage and other attributes. The chart uses `d3.scaleLinear` for both axes, `d3.extent` for domain calculation, and `d3.axisLeft` with gridlines to structure the plot.

A4_ScatterPlot

This example visualizes the relationship between study hours and exam scores using a scatter plot, where each circle represents a student. The data comes from a CSV file loaded with D3’s `d3.csv` method and filtered to exclude zero-value pairs. The SVG chart uses `d3.scaleLinear` for both axes, `d3.axisBottom`, and `d3.axisLeft` for tick marks, while circles are appended with `d3.selectAll` and `enter`. Interactive tooltips appear on mouseover, displaying the exact hours and scores for each point. All rendering is done with React-compatible vanilla JavaScript and D3 v6.
