A stacked bar chart compares average math scores across countries, segmented by parents' highest education level (ISCED categories). It uses d3.stack, d3.scaleBand, and d3.scaleLinear to render SVG bars, with color encoding via d3.scaleOrdinal. Hovering reveals a tooltip with the country’s score breakdown per education level, sourced from CSV data on father’s, mother’s, and combined parental education.

This visualization shows the effect of parental education level on students' math scores using a horizontal bar chart, with green rectangles encoding score magnitudes. The chart displays average math scores across different parental education categories, using a linear scale for the x-axis and a band scale for the y-axis. The code uses d3.csv to load the data, d3.scaleLinear and d3.scaleBand for scaling, and d3.axisLeft and d3.axisBottom for axes, rendering the visualization as SVG.

ICE 6 : bar chart for parental level of education vs math score

This bar chart visualizes the relationship between parental level of education and student math scores, with each bar representing a category of parental education. The bars are colored using a green color scale via `d3.scaleQuantize` and `colorbrewer.Greens`, with a color legend created using `d3.legendColor`. The visualization is built with D3 v7, rendering to an SVG, and reads data from a CSV file loaded via `d3.csv`. It uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with axis labels and a title added via SVG text elements.

Student_education_Piechart

This pie chart visualizes student education levels and their associated math scores, using colored slices to represent each category. The chart is built with D3 v5 and rendered as an SVG, with the `pie()` and `arc()` generators creating the segments and the `scaleOrdinal` mapping colors to data. A legend on the right displays each education level alongside its corresponding math score. Data is loaded from a CSV file via a GitHub gist, and the code includes a video tutorial link in the README.

ICE 6: Bar chart showing math scores over parental level of education.

This bar chart displays math scores as they relate to parental level of education, using data loaded via `d3.csv` from a GitHub gist. The visualization employs `d3.scaleBand` and `d3.scaleLinear` for positioning, with a `d3.scaleQuantize` color scale based on the score values to encode magnitude. Each bar’s height and fill are determined by the corresponding salary data, despite the chart’s title referencing the original dataset. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, and a categorical color legend is included via the `d3.legendColor` API.

Fork of IMDb Movie ratings

This stacked bar chart visualizes the distribution of math scores across different parental education levels. Each bar represents a parental education category, broken into stacked segments for math score ranges, with hover tooltips showing precise percentages. The visualization uses D3 v7 with SVG rendering, employing d3.stack() for data stacking, d3.scaleOrdinal for color mapping, and d3.scaleBand for categorical positioning. CSV data is loaded asynchronously via d3.csv, with the chart displaying diverging stacked bars oriented along a horizontal axis.

IC6

This visualization, part of a student performance analysis, uses D3 v7 to render two SVG charts. The first is a multi-series line chart showing how average math, reading, and writing scores trend with binned math ability, using `d3.scaleLinear` and a monotone curve. The second is a combined bar and line chart, built with `d3.rollups`, displaying score distributions across parental education levels. Data is loaded from a CSV Gist, with a categorical color scale and grid lines for clarity.

Assignment q3

This visualization shows the average reading score for students grouped by their parents' highest level of education, from some high school through master's degrees. The D3.v7 line chart uses d3.scalePoint and d3.scaleLinear for axes, with d3.mean aggregation to compute the averages. Interactive tooltips appear on hover for each data point. The chart renders as an SVG, sourced from the "StudentsPerformance 2.csv" file, highlighting the relationship between parental education and student performance in reading.

The ratio of students in the country (Primary Education)

This visualization shows the ratio of students in primary education across countries, with bars sorted in descending order to highlight the highest ratios. A bar chart rendered with SVG uses D3 v7’s `scaleBand` and `scaleLinear` to position and size the rectangles, while `d3.axisBottom` and `d3.axisLeft` display the country-year labels and ratio scale. The data is loaded from a CSV file sourced from the Global Economy and tidytuesday dataset, with bars colored steelblue and axis labels added via SVG text elements.
