Interactive scatter plot & bubble chart

By Jocelyn

A flexible, reusable chart for plotting relationships between two numeric variables in data-driven e-learning content. Authors configure everything from a simple form — no coding required — and the chart renders cleanly inside any Rise lesson. Two chart types, one tool. Choose between a scatter plot (two numeric variables, X and Y) or a bubble chart, which adds a third dimension encoded as the size of each point. Switch types at any time without losing your data or settings. In bubble mode, a control lets you set the maximum bubble size, and values are scaled by area — the mathematically honest way to represent magnitude. Data made easy. Data is provided entirely by import: paste directly from Excel, Google Sheets, or a CSV, or upload a CSV file. The chart auto-detects the separator (tab, comma, or semicolon) and accepts either a period or a comma as the decimal mark, so there's nothing to reformat. Scatter plots read two columns (X, Y); bubble charts read three (X, Y, Size). Multiple series, your way. Add as many series as you need, each with its own legend label and colour. For scatter plots, pick a point marker (circle, square, triangle, diamond, plus, cross, or star); bubble charts use filled circles. Add a calculated trend line to any series — linear, polynomial, or exponential — to highlight the underlying relationship. Built to fit your design. Customize the title and subtitle with their own fonts and sizes, label both axes, and add an independent unit suffix to the X and Y values (yrs, k$, %, mg, and so on). Adjust the fill opacity so overlapping points and bubbles stay readable. Choose the tooltip theme, the decimal separator, and the legend's position — or pick a background colour, with full transparency supported so the chart blends into any slide. Accessible by default. Every chart includes a screen-reader label adapted to the chart type, a hidden data table equivalent to the visual (including the size column in bubble mode), and a keyboard-ope
