d3.js v5 enter update not inserting rectangle div

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I am using d3.js v5 version and trying to understand enter, update. I have two data set [1,2,3.5] and other [1,2,3,4,5] . Firstly I am calling first data which renders [1,2,3.5 ] in red color and then second data is called with blue color[1,2,3,4,5] .

On update why 3 is not getting inserted in blue?

              var scale = d3.scaleLinear().domain([1,5]).range([0,200]);

            

            

              var svg = d3.select("body")

                          .append("svg")

                          .attr("width",250)

                          .attr("height",250);

            

            function render(data,color){

                 // Bind data

                 var rects = svg.selectAll("rect").data(data);

                 

                 //Enter 

                 

                rects =  rects.enter().append("rect");

                

                //update

                rects.attr("x", scale)

                .attr("y",50)

                .attr("width",20)

                .attr("height",20)

                .attr("fill",color);

            };

             

            render([1,2,3.5],"red");

            render([1,2,3,4,5],"blue");

This is because you are re-assigning rects to rects.enter(). Initially rects contains "updated" rectangles. What you want is to get both "enter" and "update", which can be done with merge.

var scale = d3.scaleLinear().domain([1,5]).range([0,200]);

            

var svg = d3.select("body")

            .append("svg")

            .attr("width",250)

            .attr("height",250);



function render(data,color){

    // update

    var rects = svg.selectAll("rect").data(data, d => d);



    // enter 

    rects

      .enter().append("rect")

      // enter + update

      .merge(rects)

        .attr("x", scale)

        .attr("y",50)

        .attr("width",20)

        .attr("height",20)

        .attr("fill",color);

};



render([1,2,3.5],"red");

render([1,2,3,4,5],"blue");

<script src="https://d3js.org/d3.v5.min.js"></script>

Edit: By default, when you call .data(...) d3 joins by index, so 3.5 becomes 3. If you want to join by numerical value , so that 3, 4 and 5 get inserted, you can pass second parameter to .data (read more

Can't say for sure. Most thorough article on selections bost.ocks.org/mike/selection has been written when v3 was introduced, also key argument to .data() and .merge() existed already in v3. So, I do not think, that there were significant changes.

in your answer 3.5 or 3 is not shown. It should have 6 rectangles after update [1,2,3,3.5,4,5]

3.5 is not coming even after the merge?

I modified answer, as far as I understand, you need to pass second argument to .data()

Looks like d3.js v3 and v4 version has some difference in the way update and enter works?

Can't say for sure. Most thorough article on selections bost.ocks.org/mike/selection has been written when v3 was introduced, also key argument to .data() and .merge() existed already in v3. So, I do not think, that there were significant changes.
