    <div class="mySeryTitle">Note on connected scatterplot</div>
    <hr>
    <p>It is of importance to understand that a connected scatterplot is basically an hybrid between a <a href="scatterplot.html">scatterplot</a> and a <a href="line-plot.html">lineplot</a>. Thus, please visit the related section <a href="scatterplot.html">here</a> and <a href="line-plot.html">here</a> to get more examples, since the techniques used are very similar.</p>
    <p>Please note also that <u>2 types</u> of connected scatterplot exist. The <u>first</u> is simply a lineplot with dots added on top of it. It takes as input 2 numeric variables only. The <u>second</u> shows the relationship between 2 numerical variables across time. It requires 3 numerical variables as input. Confusing? Visit <a href="https://www.data-to-viz.com/graph/connectedscatter.html">data-to-viz</a> to clarify.</p>

    <p>Basic R also allows to build connected scatterplot thanks to the `line()` function. You just need to use the `b` option of the `type` argument. See examples below.</p>
