d3.js - Text inside arc is misaligned/overlapped - d3.js

Question

I am drawing a pie chart and in each arc i write the text in the centre. However when the arc is too small, the text gets misaligned. How do i restrict writing the text if the arc is too thin. Is there a way to identify the arc and not write the text.
My code:
var arc = d3.svg.arc()
.outerRadius(radius - 45)
.innerRadius(radius -200);
var pie = d3.layout.pie()
.sort(null)
.value(function(d) {return d.Components;});
var g = svg.selectAll(".arc")
.data(pie(newdata))
.enter().append("g")
.attr("class", "arc")
.attr("id", function(d,i) {return "group" + i})
g.append("path")
.attr("d", arc)
.style("fill","#FFFFFF")
.transition()
.ease("bounce")
.duration(1000)
.delay(function(d, i) {return i * 500;})
.style("fill", function(d,i)
{
var c = d.data.Source;
if (c=="GREEN")
{
return "#78a22f";
}
else if (c=="RED")
{
return "#a00000";
}
else if (c=="AMBER")
{
return "#Ffb400";
}
else
{
return "#DADCF6";
}
});
g.append("text")
.attr("transform", function(d)
{
//comment
var c = arc.centroid(d);
var param,param1
param = c[1]- 20;
param1= c[0]- 38;
return "translate(" + param1 + "," + param + ")";
})
.attr("dy", ".35em")
.style("text-anchor", "middle")
.attr("style","font-family: Arial;border: solid 1px" )
.transition()
.ease("bounce")
.duration(1000)
.delay(function(d, i) {return i * 500;})
.text(function(d) {
return ((d.data.Status));
}
});
g.append("text")
.attr("transform", function(d)
{
var c = arc.centroid(d);
var param = c[1];
var param1=c[0];
return "translate(" + param1 + "," + param + ")";
})
.attr("dy", ".35em")
.style("text-anchor", "middle")
.transition()
.ease("bounce")
.duration(1000)
.delay(function(d, i) {return i * 500;})
.text(function(d) {
if (eval(d.data.Components) >0)
{
return (Number(d.data.Components).toFixed(0)) + " (" + (Number(d.data.Percentage).toFixed(1) + "%)");
}
});
data is like:
"Source","Components","Percentage","Business Unit","Status","BUId"
"RED","20","4.77","Financial & Risk - ALL","Analyzed","67001003"
"AMBER","2","0.48","Financial & Risk - ALL","Identified","67001003"
"GREEN","21","5.01","Financial & Risk - ALL","Approved","67001003"
"PALEBLUE","83","19.81","Financial & Risk - ALL","Unmapped","67001003"
"GREY","293","69.93","Financial & Risk - ALL","Not Applicable","67001003"
