feat: add scatterplot svg library #12

divisio74 · 2025-09-23T07:33:32Z

Gno Scatterplot

New Pr for the gnov package with coding style correction and new README.md

The gnov package allows you to render a scatter plot as an SVG image. It takes a list of (x, y) points and draws them as circles on a 2D canvas. You can also apply optional flags to display regression lines or curves.

API references

Testscatter(POINTS, "TITLE", "X_AXIS_TITLE", "Y_AXIS_TITLE", "FLAG")

POINTS strcuture is set with the following arguments :

   type Point struct {
       X, Y  float64 //Coordinate of the point
       Color string // Color of the point
       Label string // Associate a label to the point
   }

TITLE, X_AXIS_TITLE, Y_AXIS_TITLE are strings.

FlagRe is a Boolean value: true to enable and false by default.

Maxticks is an int n used to divide the axis into n graduation marks.

Width and height are int to personalize the size of the scatterplot.

Usage

Usecase

ScatterPlot{
        Points: []Point{
            {X: 100, Y: 00, Label: "A"},
            {X: 101, Y: 20, Label: "B"},
            {X: 102, Y: 40, Label: "C"},
			{X: 103, Y: 60, Label: "D"},
        },
        Title: "Sales Growth",
        XAxis: "Years",
        YAxis: "Sales",
        FlagRe:  true,
        maxticks: 20,
        width: 800,
        height: 800,
    }

Flags

Lineary Regression flag that display the regression line of the scatterplot can be actived by the bool true.
Each flag shows the equation of the regression in the top left of the Scatterplot.

Hey, nice idea! 🥳
I recommend you to add images in your PR for visual examples.

What means the name gnov?

Gno Visual aha but i thinks we can find a better name for this ...

If you keep the name (which I think is alright), I think it's always great to highlight what it means, so the reader can better remind of it!

As @Davphla said; rename the H1 to the full name, GnoVisual, so that it makes sense to the reader. Then, you can chose to abbreviate it if you want. I get the point of shortening names, but you should ty naming your packages so that they're recognizable from the import path. A good name would be 'p/pierre115/scatterplot` :)

Hey, can you please reply to @Davphla's comments before resolving the conversations?

@divisio74 I recommend you to add the link to the commit when replying to the comment!

Overall some missing details, but after it's fixed it should be good I think!
